Question

A 500kg car is driving through a neighborhood at 20m/s. Then the car hits a speed bump which causes it to slow to 15m/s. What was the impulse delivered by the speed bump to the car?

Answer 1

Based on the formula for calculating impulse, the impulse of the speed bump to the car is 2500 Ns.

What is the impulse of the speed bump?

• 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.
