Question

29. Four forces F1=3N, F2=2N, F3=3N and F4=6N are acting on a body of mass 30 kg as shown in
figure. Find the acceleration of the body​

Answer 1

Explanation:

The rate of change of momentum is 3 kg-m/s²

Explanation:

The horizontal forces as

N

N

N

N

If is removed

Then there will be change in momentum

From Newton's second law we know that

Rate of change of momentum = Force

Since force of 3 N is removed

Therefore, rate of change of momentum = 3 kg-m/s²

Hope this answer is helpful.
