A hockey puck of mass 0.16 kg, sliding on a nearly frictionless surface of ice with a velocity of 2.0 m/s (E), strikes a second puck at rest with a mass of 0.17 kg. the first puck has a velocity of 1.5 (N 31 E) after the collision. Determine the velocity of the second puck after the collision.

Y: 0=m₁u₁sinα - m₂u₂cosβ
m₁v₁-m₁u₁cosα = m₂u₂cosβ …(1)
m₁u₁sinα= m₂u₂cosβ ………...(2)
Divide (2) by (1)
tanβ= m₁u₁sinα/ (m₁v₁-m₁u₁cosα) =
=sinα/ (1- cosα) =3.6
u₂=m₁u₁sinα/ m₂cosβ= 0.16•2•sin31/0.17•sin 74.5 =1 m/s
