Question

A force of 10 N acts on a body for 10 sec. What will be the change in momentum? la) 2000 NS (b) 400 NS (c) 500 NS (d) 1000 NS​

Answer 1

Answer:

Answer is follow

Explanation:

Correct option is D)

F=tm(v−u)

100=102(v−u)

⇒(v−u)=500ms−1

Change in momentum =m(v−u)

=2×(500)

=1000 N−s
