Question

a body P has a mass of 2m and velocity5v another body Q has mass 8 m and velocity 1.25v the ratio of momentum of Pand Q is??

plz fast...

Answer 1

For case of body P :—

We know momentum = mass × velocity

= 2m × 5v = 10mv

Now for case of body Q :—

= 8m × 1.25v = 10mv

Therefore, the ratio of their monentum is 10 : 10

= 1 : 1
