A metal puck of mass 3.0 kilogram slides down a curved track starting 4 meter above ground. Puck is on right side of track and has initial velocity of vi. Work done by friction while on ramp is -30 Joule. Upon leaving runway puck is starveling straight up and reaches maximum height of 5 meter above ground before falling back down. Ignore air resistance
Compute the velocity of puck as it leaves runway?
Compute the total energy of puck while on ramp?
Compute the initial velocity of puck?
If ramp was frictionless, find what maximum height would puck reach after it left ramp?
