Two rubber balls with masses of 0.2 kg and 0.4 kg cometowards each other and collide. Pre-collision and post-collisionballs move in the same direction. Your balls velocities are givenas 1.5 m / s and 2 m / s, respectively.
a) Considering that the collision is elastic, the velocity of theballs after the collision and Find the directions.
b) If the time that the balls are in contact with each other duringthe collision is 0.01s, the balls What is the average force N theyapply? c) If the balls were stuck together after the collision, inwhat direction and speed would they move?
d) In this case, how many J is the energy converted into heatduring the collision?
e) What% of the total mechanical energy has been converted intoheat?
