A 030-kg puck initially at rest on a frictionless, Ask an Expert

Academics

A 0.30-kg puck, initially at rest on a frictionless horizontal surface, is struck by a 0.20-kg puck that is initially moving along the x-axis with a velocity of 9.5 m/s. After the collision, the 0.20-kg puck has a speed of 1.5 m/s at an angle of 53° to the positive x-axis.

(a) Determine the velocity of the 0.30-kg puck after the collision

magnitude
direction

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