Question

A ball moving with a momentum 15kgm/s strikes against the wall at an angle of 30°and is reflected with the same momentum at the same angle calculate impulse

Answer 1

hope this is the right answer

Answer 2

Answer:

Impulse= change in momentum

= final momentum - initial momentum

= mu cos0 -(- mucos0)

= 2mucos0

= 2×15×√3/2

= 15√3 kg m/s
