Question

a force of 10 newton act on a body of mass 20 kg for 10 secound chage its momentum is​

Answer 1

Answer:

Given : Force = 10 Newton.

Mass = 20 Kg

Time = 10 Seconds

To find :

Change in Momentum.

The change in momentum of an object is its mass times the change in its velocity.

Solution:

We know that,

F=ma

Force = ( mass * acceleration)

F=m*(v-u/t)

Ft=m(v-u)

10*10=change in momentum

Change in Momentum =100 kg.m/s
