Most modern vehicles have padded dashboards. This reduces collision injuries by...

• reducing the driver's change in momentum

• increasing the driver's change in momentum

A test crash was studied and a graph of its Force over Time was produced. If a cushion was added and the crash was repeated, what should occur to the graph?

• Force peak would increase, and time of collision would increase.

• Force peak would decrease, and time of collision would increase.

• Force peak would increase, and time of collision would decrease.

• Force peak would decrease, and time of collision would decrease.

A person on a stationary skateboard throws a bowling ball with a velocity of 5.0 m/s. Knowing that momentum should be the same in both directions since they both started with zero momentum, what is a possible speed of the person after the throw?

• 5.0 m/s

• >5 m/s
