A boat of mass 1,300 kg that is moving at a speed of 6 m/s and
a speedboat of mass 850 kg that is moving at a speed of 25
m/s. What's the total linear momentum of the boat and the
speedboat?
Answer: 29,050
Explanation:
If you notice this is a add and multiply problem .
All you are doing is finding the total linear momentum .
You would multiply 1,300 x 6= 7800
Then you would also multiply 850 x25=29050
You would add both of them (7800+21250)
And your final answer would be 29050kg •m/s

A freight train traveling with a velocity of −4.0 m/s begins backing into a train yard. If the train's average acceleration is −0.27 m/s^2 , what is the train's velocity after 17 s?
Answer:
−8.59 m/s.
Explanation:
From the question given above, the following data were obtained:
Initial velocity (u) = −4.0 m/s
Acceleration (a) = −0.27 m/s²
Time (t) = 17 s
Final velocity (v) =?
Acceleration is defined as the change of velocity with time. Mathematically, it is expressed as:
Acceleration = change of velocity / time
Acceleration = (final velocity – Initial velocity) / time
a = (v – u) / t
With the above formula, we can determine the velocity of the train after 17 s. This can be obtained as follow:
Initial velocity (u) = −4.0 m/s
Acceleration (a) = −0.27 m/s²
Time (t) = 17 s
Final velocity (v) =?
a = (v – u) / t
−0.27 = (v – –4 ) / 17
−0.27 = (v + 4 ) / 17
Cross multiply
−0.27 × 17 = v + 4
−4.59 = v + 4
Collect like terms
−4.59 – 4 = v
−8.59 = v
v = −8.59 m/s
Thus, the velocity of the train after 17 s is −8.59 m/s.

1. A rock rolls off the edge of a cliff with an initial velocity of 10 m/s.
It takes 6.5 seconds for it to hit the ground below. What is the
displacement of the rock?
Answer:
65meters
Explanation:
Given data
velocity= 10m/s
time= 6.5seconds
Applying the expression
velocity= distance/time
substitute
10=distance/6.5
distance= 10*6.5
distance= 65meters
Hence the displacement is 65meters
what happens to the horizontal component of velocity while an object is in the air.
Answer:
nothing happens
Explanation:
Horizontal component of velocity does not change (when air resistance is negligible); Vertical component of velocity changes due to GRAVITY. ... It takes the same exact amount of time and it has the same velocity but negative due to gravity.

Cellular respiration occurs in every cell of our bodies. Through this process, we obtain the energy we need for life. During cellular respiration, oxygen helps in breaking down sugar molecules into carbon dioxide and water molecules. Which reaction correctly represents the cellular respiration process?(1 point)
carbon dioxide + water → sugar + oxygen + energy
sugar + oxygen → carbon dioxide + water + energy
carbon dioxide + water + energy → sugar + oxygen
sugar + oxygen + energy → carbon dioxide + water
Answer:
B. sugar + oxygen → carbon dioxide + water + energy
Explanation:
Energy is that which sustains living organisms, so as to perform various activities. One of the processes by which living organisms produce energy is by respiration.
Respiration involves the breathing-in of oxygen and breathing-out of carbon dioxide as a waste. The oxygen helps in breaking down molecules of carbohydrates e.g sugar in the system of living organisms into energy, carbon dioxide and water.
This process is well represented by the equation in option B.
The reaction which correctly represents the cellular respiration process is sugar + oxygen → carbon dioxide + water + energy.

Consult Multiple-Concept Example 5 for insight into solving this problem. A skier slides horizontally along the snow for a distance of 12.4 m before coming to rest. The coefficient of kinetic friction between the skier and the snow is 0.0368. Initially, how fast was the skier going
Answer:
The speed with which the skier was going is approximately 2.9906 m/s
Explanation:
The given parameters are;
The distance the skier slides before coming to rest, s = 12.4 m
The coefficient of friction between the skier and the snow, [tex]\mu _k[/tex] = 0.0368
Therefore, for conservation of energy, we have;
Initial kinetic energy = Work done by the kinetic friction force
Initial kinetic energy = 1/2·m·v²
The work done by the kinetic friction force = [tex]\mu _k[/tex]×m×g×s
Where;
m = The mass of the skier
v = The speed with which the skier was going
g = The acceleration due to gravity = 9.8 m/s²
s = The distance the skier slides before coming to rest = 12.4 m
[tex]\mu _k[/tex] = The kinematic friction = 0.0368
Therefore, for conservation of energy, we have;
1/2·m·v² = [tex]\mu _k[/tex]×m×g×s
1/2·v² = [tex]\mu _k[/tex]×g×s
v² = 2×[tex]\mu _k[/tex]×g×s = 2 × 0.0368 × 9.8 × 12.4 = 8.943872
v = √(8.943872) ≈ 2.99063070271 ≈ 2.9906 m/s
The speed with which the skier was going = v ≈ 2.9906 m/s.

Answer:
For a longitudinal wave, such as a sound wave, amplitude is measured by the maximum displacement of a particle from its position of equilibrium. When the amplitude of a wave steadily decreases because its energy is being lost, it is said to be damped. So, a sound wave 's amplitude decreases as it moves through a medium.

Answer:
Yes because
Explanation:
Clouds get their shapes from the air that surrounds them. ... Since clouds are made up of millions of tiny pieces of water, when they are really high up in the sky where the air is very cold, the water droplets freeze into floating ice crystals. When we observe these clouds way up in the sky, they look like wispy strands

A 125kg man buy a 6kg watermelon, a 3kg cantaloupe, and 6kgs of potatoes, he walks home with his purchases in a large bag. His walking speed is 2.5m/s2 , what force is required for him to get home?
Answer:
350N
Explanation:
Given parameters:
Mass of the man = 125kg
Mass of the watermelon = 6kg
Mass of cantaloupe = 3kg
Mass of potatoes = 6kg
Acceleration = 2.5m/s²
Unknown:
Force required to get home = ?
Solution:
To find this force we use;
Force = mass x acceleration
mass = 125 + 6 + 3 + 6 = 140kg
So;
Net force = 140 x 2.5 = 350N

It's 5 kilometers from my house to the gym. If I walk to the gym and back home how many meters have I traveled
Answer:
10 km
Explanation:
Distance is a measurement of the length of space between two points or objects. Distance is a scalar quantity, that is it has magnitude and no direction. The S.I unit of distance is meter, but other units are inches, kilometers, mile and so on.
Total distance traveled = distance from house to gym + distance from gym back to the house
Total distance traveled = 5 km + 5 km
Total distance traveled = 10 km
