A projectile is launched from ground level to the top of a cliff which is 195 m

Question

A projectile is launched from ground level to the top of a cliff which is 195 m away and 135 m high

If the projectile lands on top of the cliff 9.2s after it is fired, find the initial velocity of the projectile (magnitude and direction). Neglect air resistance.

Determine the angle too.

Explanation / Answer

The vertical component of velocity is, vyi = vi sin34.7

Direction theta = tan^-1(25.72/37.14) = 34.7 deg
