Work Energy And Power

A stone is projected vertically upwards with velocity 'V. Another stone of same mass is projected at an angle fo \(60^{\circ}\) with the vertical with the same speed \((\mathrm{V})\). The ratio of their potential energies at the highest points of their journey, is

\(\left[\sin 30^{\circ}=\cos 60^{\circ}=0.5, \cos 30^{\circ}=\sin 60^{\circ}=\frac{\sqrt{3}}{2}\right]\)
