Question

A ball moving with a momentum of 15 kg m s strikes against a wall at 60% angle and is reflected
at the same angle with its initial speed. Find the impulse​

Answer 1

Explanation:

Impulse is nothing but change in momentum

sry for ugly pic can't draw properly

Now see momentum is changing only perpendicular to wall , along the wall both final and initial momentum in same direction (cos component)

Now let's find out Change in momentum

mvsin60-(-Mvsin60)= 2Mvsin60

2×15× √3/2

15√3 is the change in momentum or Impulse

Answer 2

Answer:

mvsin60-(-Mvsin60)= 2Mvsin60

2×15× √3/2

15√3 is the change in momentum or Impulse.
