Question

a) How does the velocity data after the collision compare to the velocity before the collision in direction and magnitude? Does this make sense?

We collided two carts on a track.
Cart A (600 g)
initial velocity: .4
final velocity: -.1

Cart B (1099 g)
initial velocity: .35
final velocity: .1

b)Do you want to land with stiff legs, or bend your knees as you hit the ground?

(Recall you are hitting the ground in both cases with the same velocity; however, one obviously hurts more, likely breaking your bones. Though the velocities are the same in both cases, the deceleration isn
