Starting Your Momentum

DoNow: A 10 kg mass moving at 5 m/s is involved in a collision that causes it to stop in 0.01 s.
(a) Calculate the average impact force experienced by the block during the collision.
(b) What happens to the force when the impact time is doubled?
(c) The other object in the collision was initially at rest has a mass of 1.0 kg, what is its new velocity? (notes)

AIM: I can identify the velocity of objects undergoing elastic or inelastic colisions and describe how to apply the concept of Momentum Conservation to collisions to quantitatively determine Impact Force, Impact time and change in mass and/or velocity relationships in a collision.
