A projectile is fired from the edge of a 20 m tall cliff at an angle of 40° above the horizontal. It lands on the ground below the cliff at a distance of 45 m from the base of the cliff. Find the initial speed of the projectile just after it was fired.

A projectile is fired from a point 50 meters from a tall cliff at 75 m/s and at an angle of 50 degrees above the horizontal. It will strike the cliff at a point h above the cliff base. What is h and at what speed will the projectile strike the cliff?
Pritesh R.
A projectile is launched at a $60^{\circ}$ angle above the horizontal on level ground. The change in its velocity between launch and just before landing is found to be $\Delta \vec{v}=\vec{v}_{\text {landing }}-\vec{v}_{\text {launch }}=-20 \hat{y} \mathrm{~m} / \mathrm{s}$. What is the initial velocity of the projectile? What is its final velocity just before landing?
