Question

A steel ball A, of mass 20.0 kg moving with a speed of 1 2.0ms

collides with

another ball B of mass 10.0 kg which is initially at rest. After collision, A moves with

a speed of 1 1.0ms

at an angle of 30º with its original direction of motion. Determine

the final velocity of B.​

Answer 1

Answer:

V1 sinThita 1 = V2 sin thita 2

thita2 = 90 -30 = 60°

thita 1 = 30

V 1 = 11m/s

11/2= v √3/2

v = 11/√3
