A 2kg box,initially at rest,is pulled along the ground by a force of 15N acting along the plane of the ground.A constant frictional force of 3N acts on the box during this motion.The box is displace 10m. Then calculate work done on the box?

To calculate the work done on the box, we can use the formula:

Work = Force * Distance

First, let's find the net force acting on the box. The net force is the force pulling the box minus the frictional force:

Net Force = Force pulling the box - Frictional force
= 15N - 3N
= 12N

Next, we can calculate the work done by this net force. Since the box is displaced 10m, we have:

Work = Net Force * Distance
= 12N * 10m
= 120 Joules

Therefore, the work done on the box is 120 Joules.
