A spring-loaded gun fires a 0.080-kg puck along a tabletop. Thepuck slides up a curved ramp and flies straight up into theair.
(a) If the spring is displaced 24.0 cm from equilibrium and thespring constant is 875 N/m, how high does the puck rise, neglectingfriction?
x = m
(b) If instead it only rises to a height of 5.00 m because offriction, what is the change in mechanical energy?
Wnc =
