The train is accelerating meaning there is a change in the velocity so the speed is either increasing or decreasing depending. The bicycle is travelling at a constant velocity meaning it is travelling at a constant speed.
Because the temperature of the place its contained in is constantly changing, for example, if you put a room temperature item in the fridge it will become cold, or whatever the temperature you set your fridge to.
Based on the formula for calculating impulse, the impulse of the speed bump to the car is 2500 Ns.
<h3>
What is the impulse of the speed bump?</h3>
- Impulse = change in momentum
- momentum = mass * velocity
Change in momentum = mu - mv
where u is initial velocity
v is final velocity
Impulse = 500 * 20 - 500 * 15
Impulse = 2500 Ns
Therefore, the impulse of the speed bump to the car is 2500 Ns.
