A projectile is shot from the edge of a cliff 285 m above, Ask an Expert

Academics

A projectile is shot from the edge of a cliff 285 m above ground level with an initial speed of vo=115 m/s at an angle of 35.0° with the horizontal.

(a) Determine the time taken by the projectile to hit point P at ground level.
(b) Determine the distance X of of point P from the base of the vertical cliff.
(c) At the instant just before the projectile hits point P, find the horizontal and the vertical components of its velocity. (Assume the positive directions are upward and to the right.)
(d) At the instant just before the projectile hits point P, what is the magnitude of the velocity?
(f) Find the maximum height above the cliff top reached by the projectile.
