A 200-g hockey puck is launched up a metal ramp that is inclined at a 30 degree angle. The coefficents of static and kinetic friction between the hockey puck and the metal ramp are 0.40 and 0.30, respectively. The puck's initial speed 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?
