Question

If a force of 50N is applied on a body of mass 50kg which decreases its velocity from 80m/s to 75m/s then find the time taken by the force to bring this change in the velocity?​

Answer 1

Answer:

5sec

Explanation:

1. f=ma. 50n=50*5/t t=5sec

Answer 2

Answer:

5 sec

Explanation:

f =ma

50N=50(a)

50N=50(v-u)/t

50N=50(80-75)/t

50N=50(5)/t

t=5
