Question

How much force is required to produce impulse of 1 NS, if that force will acts for 0.02 sec

​

Answer 1

Answer:

40N

Step-by-step explanation:

Mass, m=2kg

Initial velocity, u=0

Final velocity, v=2m/s

Change in velocity, Δv=v−u=2m/s

Time interval, Δt=0.1s

Acceleration, a=  

Δt

Δv

​

=  

0.1

​

=20m/s

Force, F=ma=2kg×20m/s

=40N
