Question

If a force of 1000 N is applied over a vehicle of 500 kg. then for how much time the velocity of the vehicle will
increase from 2 m/s to 10 m/s. Also find the impulse.​

Answer 1

Answer:

f=ma

f=m dv/dt

f=500 10-2/dt

f=500*8/dt

1000=4000/dt

dt=4000/1000

dt=4sec

impulse =f*time interval

I=f(t)

I=1000*4

I=4000 Newton second
