A stone is projected at a cliff of height h with an initial speed of 30.0 m/s directed at angle 60.0 degrees above the horizontal. The stone strikes at point A, 4.0 s after launching. a. Find the horizontal component of the stone’s initial velocity in m/s.
b. Find the vertical component of the stone’s initial velocity in m/s.
c. Find the height H in meters.
d. Find the height h of the cliff.
e. Find the speed of the stone (in m/s) just before impact at point A.
