Question

A ball moving with a speed of 9m/s strikes
an identical ball at rest such that after the
collision the direction of each ball makes an
angle of 30 with the original line of motion

b) find the loss of kinetic energy in perfectly
inelasatic collision​

Answer 1

Answer:

hii.. dear friend..

here is ur answer..

hope it will help you..

Explanation:

By momentum conservation in Y-direction.

mv

1

sin30−mv

2

2sin30=0

v

1

=v

2

In X direction,

mu

1

=mv

1

cos30+mv

2

cos30

m×3=2mv
