A 0.400-kg ice puck, moving east with a speed of 5.18 m/s , has a head-on collision with a 0.900-kg puck initially at rest. Assume that the collision is perfectly elastic.
a)What is the speed of the 0.400- kg puck after the collision?
b) What is the direction of the velocity of the 0.400- kg puck after the collision?
c)What is the speed of the 0.900- kg puck after the collision?
d) What is the direction of the velocity of the 0.900- kg puck after the collision?
