Physics - Kinematics Question with Solution | TestHub

A boy playing on the roof of a $10\mathrm{m}$ high building throws a ball with a speed of $10\mathrm{m}/\mathrm{s}$ at an angle of $30^{\circ }$ with the horizontal. How far from the throwing point will the ball be at the height of $10\mathrm{m}$ from the ground? $$\left[\mathrm{g}=10\mathrm{m}/{\mathrm{s}}^2,\sin 30^{\circ }=\frac{1}{2},\cos 30^{\circ }=\frac{\sqrt{3}}{2}\right]$$
