Physics

A 0.30-kg puck, initially at rest on a frictionless horizontalsurface, is struck by a 0.20-kg puck that is initially moving alongthe x-axis with a velocity of 9.0 m/s. After the collision, the0.20-kg puck has a speed of 5.4 m/s at an angle of θ = 53° to thepositive x-axis.

a)Determine the velocity of the 0.30-kg puck after thecollision.

magnitude-?

direction-? (from the positive X-axis)

(b) Find the fraction of kinetic energy lost in thecollision.
