Forces and equilibrium — practice question
A block is drawn across level ground in a straight path by a force of fixed magnitude that acts at an angle of $60^{\circ}$ above the horizontal. The work done by the force in moving the block through $5\,\text{m}$ is $75\,\text{J}$.
(main)[3]
Determine the magnitude of the force.
