Answer:
The magnitude of the impulse vector of the bat is 29.346 kg.m/s
The direction of the impulse vector of the bat is in the initial direction of the ball before impact
Explanation:
The given parameters are;
The mass of the ball, m₁ = 438 g
The speed of the ball = 39 m/s
The mass of the softball bat = 2.4 kg
The time of contact = 302 ms = 0.302 seconds
The speed of rebound = 28 m/s
The impulse = The change in momentum = Δp = F × Δt = m × Δv
The impulse on the ball = m₁ × Δv = 0.438 × (39 - (-28)) = 29.346 kg·m/s
Given that force of reaction of the bat is in opposite direction but equal to the force of the ball, and the time and the duration of contact with the ball is the same for both the ball and the bat, the impulse vector ore equal and opposite
Therefore, the magnitude of the impulse vector of the bat = 29.346 kg.m/s
The direction of the impulse vector of the bat = The initial direction of the ball before impact.

If you run a complete loop around an outdoor track of length 400 m in 100 s, find your(a) average velocity and (b) average speed. *
Answer:
a) 0 m/s
b) 4 m/s
Explanation:
The average velocity would end up being 0 because it is displacement over time and the displacement here is 0. However, speed is total distance over time which here is 400/100 so it is 4.

Two persons A and B are walking with speed 5 km/h and 6 km/h
respectively in the same direction. Find how far will B be from A after
2 hours.
a 6 km
b 2 km
C 5 km
d 3 km
Answer:
b
Explanation:
The relative distance can calculate by dividing the time travelled by the speed difference between points A and B. Considering that B is going more quickly than A, we substract A's speed from B's speed.
Relative Speed = Speed of B - Speed of A
Relative Speed = 6 km/h - 5 km/h
Relative Speed = 1 km/h
Now, we can calculate the relative distance traveled by B after 2 hours:
Relative Distance = Relative Speed * Time
Relative Distance = 1 km/h * 2 hours
Relative Distance = 2 km
Therefore, B will be 2 kilometers away from A after 2 hours of walking in the same direction.

Calculate the normal force and force applied of a box that has a mass of
50kg and that is moving rightward with an acceleration of 7.2m/s^2
Heya!!
For calculate force, lets applicate second law of Newton:
[tex]\boxed{F=ma}[/tex]
Δ Being Δ
F = Force = ?
m = Mass = 50 kg
a = Aceleration = 7,2 m/s²
⇒ Let's replace according the formula:
[tex]\boxed{F= 50\ kg * 7,2 m/s^{2}}[/tex]
⇒ Resolving
[tex]\boxed{ F = 360\ N}[/tex]
Result:
The force is 360 Netwons.

true or false. because the speed of an object can change from one instant to the next, dividing the distance covered by the time of travel gives constant speed
true. Because the speed of an object can change from one instant to the next, dividing the total distance covered by the time of travel gives. average speed.
Answer:
False.
Explanation:
Dividing the distance covered by the time would give us the average speed, not a constant speed. Constant speed exists only if the speed of an object does not change.

A ships initial position is 25 km east of the origin. What is the ship’s final position if it sails at a constant velocity of 42 km/h east in exactly 1.5 h? (Note: answer in km)
Answer:
88km E
Explanation:
25 km is added already
then if we take the formula of speed(V)
V=d/t
and rearrange it to subject d (distance)
d= V x t
we get
d= 42km/h x 1.5hrs
we get
63 km
now if we add the already travelled 25 km to this additional distance
63km + 25km = 88km
Thus the final distance traversed by the ship from its origin is
88km E

Write a scientific explanation that describes the interaction between the two skaters caused by the forces that they apply to each other.
Explanation:
... in every interaction, there is a pair of forces acting on the two interacting objects. The size of the force on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs.
