Question

. A ball of mass 1 kg moving with a speed
of 10 ms rebounds after a perfect elastic
collision with the floor. Calculate the
change in linear momentum of the ball. using m ×v​

Answer 1

Answer:20kgm/s

Explanation:

As the ball is elastically rebounded ...so no loss of energy occurs

U = 10m/s

V = (-10) m/s [ negative means the opposite direction]

So ∆V = 10-(-10)

=20 m/s

So momentum =mv

=1*20

So ans is 20kgm/s
