A 200 g hockey puck is launched up a metal ramp that is inclined at a 30° angle. The coefficients of static and kinetic friction between the hockey puck and the metal ramp are ,us = 0.40 and pk = 0.30, respectively. The puck's initial speed is 63 m/s. What vertical height does the puck reach above its starting point?
