Answer:
h = 181.73 m
Explanation:
given,
distance between the neighbors = 42 m
speed of the rock rolling = 6.9 m/s
vertical velocity of ball = 0 m/s
height of the cliff = ?
time taken by the ball to travel 42 m
d = s x t
s is the horizontal speed of the ball equal to 6.9 m/s


t = 6.09 s
same time will be taken by the ball to travel vertical distance
Using equation of motion



h = 181.73 m
