Question

A ball of mass 1kg , moving with a velocity of 0.4m/s collides with another stationary ball. After the
collision, the first ball moves with a velocity of 0.3m/s in a direction making an angle of 90° with its initial
direction. The momentum of second ball after collision will be (in kg-m/s)
(a) 0.1
(b) 0.3
(c) 0.5
(d) 0.7​

Answer 1

Answer:

0.1

Explanation:

it is a elastic collision as the angle is 90

Answer 2

Answer: romba kevalamana answer thaan ethuku (0.5m/s)

Explanation: ball 1kg velocity 0.4m/s 1st ball velocity 0.3m/s angle 90°

Momentum P= m × v = 0.5m/s
