A 0.228 kg puck, initially at rest on a horizontal, frictionless surface, is struck by a 0.228 kg puck moving initially along the x axis with a speed of 2.27 m/s. After the collision, the 0.228 kg puck has a speed of 1.27 m/s at an angle of 31◦ to the positive x axis. Determine the magnitude of the velocity of the 0.228 kg puck after the collision. Answer in units of m/s.

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
