- A In A Perfectly Elastic Collision A 0 400 Kg Ball Moving Toward The East At 3 7 M S Su Collides Head On With A 0 200 K 1 (133.89 KiB) Viewed 20 times
a In a perfectly elastic collision, a 0.400 kg ball moving toward the east at 3.7 m/s su collides head-on with a 0.200 kg ball sitting at rest. (a) Determine the velocity of the first ball just after the collision (5 points) (b) Determine the velocity of the second ball just after the collision (5 points) (c) Is kinetic energy conserved in this collision? How do you know? Show work (5 points) (d) If the second ball is sitting initially at rest right at the edge of a 1.2 m tall table, what will it velocity be as it hits the ground? (5 points)
