Two hockey pucks collide on a horizontal, frictionlešš šurface. T he velocities of both pucks before the collision are shown in the drawing. After they collide, puck A is moving as shown. Assume that the mass of puck A is four times as large as the mass of puck B: MA = 4*MB. a) Find the magnitude and direction of the velocity of puck B after the collision. Clearly indicate on your drawing the angle you are using to specify the direction of puck B. b) Is in this collision purely elastic or not? Justify your answer with calculation.

Question
Two hockey pucks collide on a horizontal, frictionlešš šurface. T he
velocities of both pucks before the collision are shown in the drawing.
After they collide, puck A is moving as shown. Assume that the mass of
puck A is four times as large as the mass of puck B: MA = 4*MB.
a) Find the magnitude and direction of the velocity of puck B after
the collision. Clearly indicate on your drawing the angle you are
using to specify the direction of puck B.
b) Is in this collision purely elastic or not? Justify your answer
with calculation.
