Q13MEnergy, Work and PowerFree sample

A block is pulled in a straight line along horizontal ground by a force of constant magnitude acting at an angle of $60^{\circ}$ above the horizontal. The work done by the force in moving the block a distance of $5\text{ m}$ is $75\text{ J}$ . Find the magnitude of the force.
