Asked by Reyansh

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

Use conservation of momentum:

m1 v1 + m2 v2 = (m1 + m2) v_f

(5 kg)(3 m/s) + (5 kg)(0) = (5+5) v_f
15 = 10 v_f
v_f = 15/10 = 1.5 m/s

So they move together at 1.5 m/s in the original direction of object 1.
