A bumper pushes on a cart with an average force of 200 N for 0.05 s. What impulse does it give, Ari?
A bumper pushes on a cart with an average force of 50 N for 0.4 s. What impulse does it give, Bo?
A bumper pushes on a ball with an average force of 1200 N for 0.01 s. What impulse does it give, Esme?

The same cart is stopped in 0.5 s by foam or in 0.05 s by wood. How do the average forces compare, Ren?
- They are equal
- Foam: 10 times smaller
- Wood: 10 times smaller
- Foam: 10 times bigger
To stop the same cart with half the average force, what must happen to the stopping time, Tala?
- It must quadruple
- It must halve
- It must double
- It stays the same
