A particle is moving in a straight line under the action of a force given by where the force is measured in newtons and the displacement is measured in metres. Calculate the work done by the force when the particle moves from to .
The figure shows the relation between a force , measured in newtons, acting on a body and the distance , in metres, travelled by that body. Determine the work done between and .
A block moves in a straight line under the action of a force , where metres is the displacement of the body from its initial position. The work done by the force in moving the block from to is 34 J. Determine the work done by in moving the block from to .
