A spring is used to propel a 0.400-kg hockey puck across level (frictionless) ice that becomes a rough (not frictionless) ramp inclined at 27°. The puck is pushed to the left, compressing the spring, and is released and allowed to slide across the ice and up the ramp.
(a) If the puck reaches a maximum vertical height of 14 cm on the ramp, what distance does it travel along the ramp?
(b) If the puck's speed on the ice is 1.88 m/s, how much work is done by the frictional force between the ramp and the puck? Include the correct sign.
(c) What is the coefficient of kinetic friction between the ramp and the puck?
