A metal puck of mass 3.0 kilogram slides down curved track starting 4 meter above ground with initial velocity of vi. Work done by friction while on ramp is -30 Joule. Upon leaving runway puck traveling straight upward reaches maximum height of 5 m above ground before falling back down.
Determine velocity of puck as it leaves runway?
Determine total energy of puck while on ramp?
Determine initial velocity vi of puck?
If ramp was frictionless determine what maximum height would puck reach after it left ramp?
