Answer 1

Answer:

1.25 m/s

Explanation:

let the masses of bodies are m = 100g & n = 200g and

velocities are u1 = 2 m/s , v1 = 1 m/s 7 after collision u2 = 1.5 m/s , v2 = ?

formula: mu1 + nv1 = mu2 + nv2

100(2) + 200(1) = 100 (1.5) + 200(v2)

200 + 200 = 150 + 200v2

400 = 150 +200v2

200v2 = 400 - 150 = 250

v2 = 250/200 = 1.25 m/s
