Question

A force of 50N acts on a stationary body of mass 10kg for 2 seconds. Find the acceleration produced in the body and the velocity attained by it.

Answer 1

F=50N
m=10kg
t=2 seconds

F=ma
50=10a
a=50/10
a=5m/s square

a=v/t
5=v/2
v=5*2
v=10m/s

Answer 2

Here, f=50Nand mass=10kg
We know that, f=ma
50N=10a
=> a=50/10
So, a=5m/s^2


Now,a=10andt=2s
a=v/t
10=v/2
v=10×2
v=20m/s
