Object 1 has a velocity of 3m/s and a mass of 5kg. Object 2 also has a mass of 5kg but isn't moving. Object 1 collides with Object 2 and they move off together. Work out their speed using the principle of conservation of momentum.

Answer 1

M1*V1 + M2*V2 = M1*V + M2*V

5*3 + 5*0 = 5*V + 5*V
Solve for v.

Answer 2

23mph

Answer 3

The answer is 1.5m/s

Answer 4

Thank you very much
