A 2.50 kg puck travelling to the right at 3.0 m/s collideswith a 1.5 kg puck travelling to the left at 5.0 m/s. If thepucks are travelling over a frictionless surface and the collisionis inelastic, how fast will the pucks move after colliding? Thanks much!

Explanation / Answer
Given that the mass of puck is m1 = kg and m2 = kg initial velocity is u1 = 3.0m/s and u2= -5.0m/s ------------------------------------------------------------------------ Apply conservation of momentum m1 *u1 + m2*u2 = ( m1 +m2)V V = [ m1 *u1 + m2*u2 ] / ( m1 +m2) = --------- m/s
