define work give s i unit of work calculate the work done in pushing a cart through a distance of 56 m against the force of on equal to 250 N . also state the type work done.
Sarita live on 3rd floor of building at the highest of 15 M careers here school bag waiting 5.2 kg from the ground floor to hear house find the amount of work done by
her and identify the for agent which she has done work(g=10 ms -2)

Work is said to be done when a force applied on a body causes displacement in the body.

The S.I unit of work is joule.

Work = force * displacement
         = 250 N * 56 m
         = 14000 J

The work done here is negative because the displacement is the direction which is opposite to the direction of force.

Work done by Sarita =  mass * gravity * height
                                  = 5.2 * 10 * 15
                                  = 780 J
