Answer:
Explanation:
a ) For horizontal displacement
displacement = 16 m
acceleration a = 0
velocity = 8 m /s
time to cover horizontal displacement = time of flight
= displacement / velocity
= 16 / 8 = 2 s
time of flight t = 2 s
b )
for vertical displacement
initial velocity u = 0
time of flight t = 2 s
height h
h = ut + 1/2 g t²
= 0 + .5 x 9.8 x 2²
= 19.6 m
height of cliff = 19.6 m .
