Question

a student carries a bag of 5kg and moves 500m on a straight road. Calculate his work done against the gravitational force. (g = 10 m/s^2)​

Answer 1

Given data :

Mass of bag , m : 5kg

Displacement covered , s : 500 m

Force , F : mg so ( 5kg ) ( 10m/s²)

=50 N

To find :

Work , W :?

Now as we know:

W= Fs

so put

W = ( 50 N ) ( 500m )

W = 25000 Nm
