A bead of mass m = 42.5 kg is released from point A which is located 5 m above the ground and slides on the frictionless track as shown in the figure. Determine the beads speed when it reaches point C which is located 2.0 m above the ground.

Answer 1

dropped 3 meters
if no friction
(1/2) m v^2 = m g h

v = sqrt (2 g h)

Answer 2

almost 8 m/s (in my head)
