A 0.275 kg puck, initially at rest on a frictionless horizontal surface, is struck by a 0.220 kg puck that is initially moving along the x axis with a velocity of 2.03 m/s. After the collision, the 0.220 kg puck has a speed of 1.14 m/s at an angle of q = 51.0o to the positive x axis. Determine the velocity of the 0.275 kg puck after the collsion.Calculate the magnitude of the angle with respect to the x-axis and find the percentage of the kinetic energy lost in the collision.
Compute magnitude and direction of magnetic field produced by the moving belt at a point just above its surface .
