Question

what is the time interval required to increase the velocity of a body having mass 5 kg from 10 metre per second to 22 metre per second under the action of force of 30 Newton​

Answer 1

Answer:

2sec

F=ma

F=m× v-u/t

30=5×22-10/t

30/5=12/t

6=12/t

t=12/6

t= 2sec

Answer 2

Answer:

F= 30N , v = 22m/s ,

u = 10m/a m = 5kg

Force = Mass × acceleration

30 = 5 × (v-u/t)

30 = 5 × ( 22 - 10/t)

30t = 5 × 12

30t = 60

t = 60/30

t = 2s

It requires 2s
