To find the height of the cliff, we can use the kinematic equation:
h = (1/2)gt^2
Where:
h = height of the cliff
g = acceleration due to gravity (9.81 m/s^2)
t = time taken for the stone to reach the bottom of the cliff (3s)
Plugging in the values, we get:
h = (1/2)(9.81)(3)^2
h = (1/2)(9.81)(9)
h = 44.145
Therefore, the height of the cliff is approximately 44 meters.
