Problem

A projectile is projected with speed uu at an angle of 60∘60^\circ with the horizontal from the foot of an inclined plane. If the projectile hits the inclined plane horizontally, the range on the inclined plane is (1) u2212g\frac{u^2\sqrt{21}}{2g} (2) 3u24g\frac{3u^2}{4g} (3) u22g\frac{u^2}{2g} (4) 21 u28g\frac{\sqrt{21}\,u^2}{8g}
