Q. A ball is thrown horizontally from a cliff such that it strikes the ground after 5s. The tine of sight makes an angle 37$^\circ$ with the horizontal. The initial velocity of projection in $ms^{-1}$ is.

Motion in a Plane

Solution:

Tan $\theta = \frac{h}{R}$, T = $\sqrt{\frac{2h}{g}}$ and R - uT.
