brainliest pweaseee
Answer:
Yes (and no)
Explanation:
Hey! This according to my theory is possible, the g-force of an object or "elevator" (in your explanation) is accelerating as it's gravitational pull is getting stronger. So it would but wouldn't be possible in a small elevator, because you-know it's an elevator (and of course you would bump your head, ouch!) ; p !
But if you had free or spare space to use, then you can jump upwards at the last second to cancel out the gravitational pull as if you actually (or originally) jumped from this height. But the gravitational pull may be too strong for those of humans, if the person acquiring and accelerating in G-Force doesn't have good leg muscle then he may be pulled along with the object by the gravitation.
I hope this helped! Pls Brainliest my answer! It would mean and help a lot! ; )

Explanation:
Did the practice
(1) The fighters wear padded gloves to protect their hands because there is an equal and opposite force impacting the hand.
(2) The two balls when collide in a closed system will exert equal and opposite force.
(3) When the mass of the object increases, the velocity of the object will decrease to conserve momentum.
(4) The equation for calculating the momentum of an object is P = mv
(5) The momentum of the ball is 100 kg.m/s
(6) The train cars move together in the direction the large car was moving.
(7) The conservation of momentum of two objects is [tex]m_1v_1 - m_2v_2= 0[/tex]
(8) The sum of two vectors can be found by drawing the vectors perpendicular to each other.
(9) A closed system can be changed without changing the net force on the system by increase the mass and decrease the acceleration by the same numeric values.
(10) Acceleration is defined as the change in velocity over time.
(11) As ball rolls down at constant velocity, the ball has no net force acting on it.
(12) The conservation of momentum of the object is [tex]m_1v_1_i + m_2v_2_i = m_1v_1_f + m_2v_2_f[/tex]
(1)
According to Newton's third law of motion, action and reaction are equal and opposite.
The fighters wear padded gloves to protect their hands because there is an equal and opposite force impacting the hand.
(2)
Based on the principles of conservation of linear momentum, the two balls when collide in a closed system will exert equal and opposite force.
(3)
The principles of conservation of linear momentum is written as;
[tex]m_1u_1 + m_2u_2 = m_1v_1 + m_2v_2[/tex]
when the mass of the object increases, the velocity of the object will decrease to conserve momentum.
(4)
The equation for calculating the momentum of an object is written as;
P = mv
(5)
The momentum of the ball is calculated as follows;
P = mv
P = 50 x 2
P = 100 kg.m/s
(6)
For inelastic collision, the collided two objects move in the same direction after collision usually in the direction of heavier object.
The train cars move together in the direction the large car was moving.
(7)
The conservation of momentum of two objects is written as;
[tex]m_1v_1 = m_2v_2\\\\m_1v_1 - m_2v_2 = 0[/tex]
(8)
The sum of two vectors can be found by drawing the vectors perpendicular to each other.
(9)
A closed system can be changed without changing the net force on the system by increase the mass and decrease the acceleration by the same numeric values.
(10)
Acceleration is defined as the change in velocity over time.
(11)
At constant velocity , acceleration = 0
∑F = ma
∑F = m x 0
∑F = 0
Thus, as ball rolls down at constant velocity, the ball has no net force acting on it.
(12)
The conservation of momentum of the object is written as;
[tex]m_1v_1_i + m_2v_2_i = m_1v_1_f + m_2v_2_f[/tex]

Odysseus has returned from his epic voyage across the seas and gets off his boat at the end of a 50 meter pier. His beloved Penelope is waiting at the far side of the pier, at the origin. At the same time they see each other and race towards each other, meeting in a fierce embrace. Odysseus, exhausted from his journey, is able to run at 4 m/s, while Penelope can run at 6 m/s. Write an equation of motion for Odysseus.
Answer:
We know that:
Distance between Odysseus and Penelope = 50m
Speed of Odysseus = So = 4m/s
Speed of Penelope = Sp = 6m/s.
Now we want to find the equation of motion for Odysseus.
First, let's find the amount of time that he is moving, we know that when he meets with Penelope, he will stop moving.
Now they weel meet each other when the total distance traveled by both of them is equal to 50m.
Then, recalling that:
Distance = Time*speed.
50m = 4m/s*t + 6m/s*t = 10m/s*t
t = 50m/10m/s = 5s
They will move for 5 seconds.
Now we can write the movement equation for Odysseus as:
p(t) = 4m/s*t + p0 for (0s ≤ t ≤ 5s)
Where p0 is the initial position of Odysseus, and because we can put our coordinate axis where we want, we can define p0 = 0m.
Then the position of Odysseus is:
P(t) = 4m/s*t if 0s ≤ t ≤ 5s
P(t) = 4m/s*5s = 20m if t > 5s.
The second piece says that for t larger than 5 seconds, he will not move (at least for a given amount of time)

You go on American Eagle at Six Flags. The highest drop is 44.8 meters tall. It takes you 1.49 seconds to make that drop. How fast did you go?
Given parameters:
Height = 44.8m
Time to drop = 1.49s
Unknown:
Speed of drop = ?
Solution:
The is a speed problem.
Speed is one of the physical quantities. It is designated a scalar because it has magnitude but no directional orientation.
Speed is the distance divided by time.
In this problem distance is the same as the height of the drop.
Mathematically;
Speed = [tex]\frac{distance}{time}[/tex]
So, input the parameters and solve;
Speed = [tex]\frac{44.8}{1.49}[/tex] = 30.1m/s
The drop recorded a speed of 30.1m/s

A 25 N force is applied to a 1.4 kg mass on level ground. If a 5 N frictional force is present between the surface and the object, what is the magnitude of the acceleration of this object?
Given parameters:
Force applied to the mass = 25N
Mass of the body = 1.4kg
Frictional force = 5N
Unknown:
Acceleration of the object = ?
Solution:
The net force on the object;
Fapplied - Frictional force = net force (m x a)
m is the mass of the body
a is the acceleration
Input the parameters and solve;
25 - 5 = 1.4 x a
1.4a = 20
a = [tex]\frac{20}{1.4}[/tex] = 14.3m/s²
The magnitude of the acceleration of the object is 14.3m/s²

Explanation:
A rocket has a mass of 15 kg and travels a distance of 250 meters in 13 seconds before it explodes.
What is the velocity of the rocket?
And
What is the momentum of the rocket?
Answer:
1. Velocity = 19.2m/s
2. Momentum = 288 Kg/ms-¹
Explanation:
1. The velocity of the rocket can be calculated by using the formula:
V = d/t
Where v = velocity/speed (m/s)
d = distance (m)
t = time (s)
Based on the provided information, d = 250m, t = 13s
v = 250/13
v = 19.231
v = 19.2m/s
2. The momentum of the rocket can be calculated thus:
p = m × v
Where;
p = momentum (Kg/ms-¹)
m = mass (kg)
v = velocity (m/s)
Based on the information, we have v= 19.23m/s, m = 15kg
p = 15 × 19.2
p = 288 Kg/ms-¹
.
