A 200g hockey puck is launched up a metal ramp that is inclined at a 30 degree angle. The coefficients of static and kinetic friction among the puck and the ramp are μs =0.40 and μk = 0.30, and the puck's initial velocity at the base is 3.8 m/s parallel to the sloping surface of the ramp. What speed does the puck have when it slides back down to its starting point?
