Question

calculate the work done required to drag a stone if mass 30kg on the ground through a distance of 50m.(Take acceleration due to gravity = 10m/s²).​

Answer 1

Answer: Work done= F.d

= 15000 J

Explanation:

Work done= Force*distance

where

Force= mass*acceleration

mass=30kg, acceleration= 10 m/s^2, distance

=30*10

=300 N

then by formula of work done

Work done= F.d

= 300*50

=15000J
