If impulse = force x time and S.I. unit of force is newton (N), then S.I. unit of impulse is __________.
Hence, the SI unit of impulse is Newton-second (N-s).
If impulse=force×time, the SI unit of impulse is ______.
If Force (F), velocity (V) and acceleration (A) are taken as the fundamental units instead of mass, length and time, express pressure and impulse in terms of $F, V and A
A 20kg body is pushed with 7N for 1.5sec then with a force of 5N for 1.7dec and finally with a force of 10N for 3sec,the total impulse applied to the body and change in velocity will be
