Work Energy And Power

A stone is projected vertically upwards with speed '\(v\)'. Another stone of same mass is projected at an angle of \(60^{\circ}\) with the vertical with the same speed '\(v\)'. The ratio of their potential energies at the highest points of their journey is \(\left[\sin 30^{\circ}=\cos 60^{\circ}=0.5, \cos 30^{\circ}=\sin 60^{\circ}=\frac{\sqrt{3}}{2}\right]\)
