Question
A body of mass 20 kg moving with a velocity of 80 m/s collied with another body mass of 5
kg moving with a velocity of 50 m/s. If they move together after colision. Find common velocity.

Momentum = M1*V1-M2*V2 = 20*80-5*50 = 1350.
M1*V + M2*V = 1350
20*V + 5*V = 1350
25V = 1350
V = 54 m/s.
M1*V + M2*V = 1350
20*V + 5*V = 1350
25V = 1350
V = 54 m/s.
