Question

of mass 2 kg is projected with velocity 20 metre per second and the angle 60 degree with the horizontal its Momentum at the highest point is​

Answer 1

Answer:

20kgm/s

Explanation:

At highest point velocity of projectile = vcos(theta)

where (theta) is the angle if projectile with the horizontal at the time of projection

Therefore momentum at highest point is p=mvcos(theta)

You should solve yourself vso that you can gain confidence in examination

Thanks
