Question

Two blocks are free to slide along the frictionless wooden track shown below. The block of mass m1 = 5.10 kg is released from the position shown, at height h = 5.00 m above the flat part of the track. Protruding from its front end is the north pole of a strong magnet, which repels the north pole of an identical magnet embedded in the back end of the block of mass m2 = 11.0 kg, initially at rest. The two blocks never touch. Calculate the maximum height to which m1 rises after the elastic collision.
m

Explanation / Answer

given;
m1 = 5.10 kg
m2 = 11 kg
elastic collision ( restitutive coefficient e = 1)

principle of conservation energy

consider at free body of mass m1

Energy at A = Energy at B

m1 g h =
