Problem

A constant force slides a

4.0\,\text{kg}

block

2.5\,\text{m}

along a level surface. The force acts at

60^{\circ}

above the direction of motion and does

60\,\text{J}

of work on the block. What is the magnitude of the force? (a)

24\,\text{N}

(b)

75\,\text{N}

(c)

48\,\text{N}

(d)

30\,\text{N}
