A 0.284 kg puck, initially at rest on a horizontal, frictionless surface, is struck by a 0.248 kg puck moving initially along the x axis with a speed of 3.03 m/s. After the collision, the 0.248 kg puck has a speed of 2.03 m/s at an angle of 23 degree to the positive x axis. Determine the magnitude of the velocity of the 0.284 kg puck after the collision. Answer in units of m/s.
A 10kg mass initially at rest explodes into three pieces. A 4.5kg piece goes north at 20 m/s and a 2.0kg piece moves eastward at 60 m.s. A) Determine the magnitude and direction of the velocity of the third piece. B) Compare the final Kinetic Energy of the system to the original kinetic energy of the system.
