Sustaining Momentum

DoNow: A 2 kg object experiences a perfectly elastic collision and bounces off of a wall with a speed of 1.25 m/s.
(a) What happens to the velocity before and after the collision.
(b) Calculate the momentum of the object before and after the collision.
(c) Calculate the change in momentum of the object.
(d) Describe the Impulse of the object.
(e) If the collision takes 0.01 s determine the impact force.
(notes)

AIM: I can describe when and how to apply the impulse-momentum theorem to predict the motion of objects in a collision or explosion type scenarios.
