Question

A girl does a work of 500 J is pushing a cart move a distance of 20 m. What is the magnitude of force applied bythegirl?

Answer 1

Given :

Work done = 500 J

Distance covered = 20 m

To Find :

Magnitude of force applied by the girl

Solution :

We know,

              Work done = Force * Displacement

                         500 = force * 20

                      Force = 500/20 = 25 N

Therefore, the force applied by the girl in moving the cart is 25 N
