A 0300 kg puck initially at rest on a horizontal, Ask an Expert

Academics

A 0.300 kg puck, initially at rest on a horizontal, frictionless surface, is struck by a 0.200 kg puck moving initially along the x axis with a speed of 2.00 m/s. After the collision, the 0.200 kg puck has a speed of 1.00 m/s at an angle of ? = 55.0° to the positive x axis (Fig. 8.11).

(a) Determine the speed of the 0.300 kg puck after the collision.

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