Question

Initially a body of mass 'm' is moving with 'v' velocity if by applying force if its velocity if by applying force if its velocity becomes one-third of initial then the ratio of old and new momentum is.

Answer 1

Answer:

3:1

Explanation:

momentum = mass * velocity

p = mv (initial momentum)

p = m*$\frac{v}{3}$

Ratio = $\frac{mv}{\frac{mv}{3} }$

∴ Ratio = 3:1
