A projectile is shot from the edge of a cliff 115 m above
ground level with an initial speed of 65.0 m/s at an angle of
35.0° with the horizontal, as shown in Fig. 3–51. (a) Deter-
mine the time taken by the projectile to hit point P at
ground level. (b) Determine the distance X of point P
from the base of the vertical cliff. At the instant just before
the projectile hits point P, find (c) the horizontal and the
vertical components of its velocity, (d) the magnitude of
the velocity, and (e) the angle made by the velocity vector
with the horizontal. (f) Find the maximum height above
the cliff top reached by the projectile.

(i) A particle is launched into the air from the ground with launch speed 8 m/s. The speed of the particle at maximumheight is 4 m/s. Find
a) the launch angle. b) maximum height reached by the particle. c) range of the particle.
(ii) In projectile motion, what assumption makes the horizontal speed constant?
A projectile is launched from ground level to the top of a
cliff which is 195 m away and 135 m high (see Fig. 3–56).
If the projectile lands on top of the cliff 6.6 s after it is
fired, find the initial velocity of the projectile (magnitude
and direction). Neglect air resistance.
