Answer:
240.1m
Explanation:
Given parameters:
Time taken to hit the ground = 7s
Unknown:
Height of the cliff = ?
Solution:
To solve this problem, we use the right motion equation expressed below:
S = ut + gt²
S is the height of the cliff
u is the initial velocity = 0m/s
g is the acceleration due to gravity = 9.8m/s²
t is the time taken
Now, insert the parameters and solve the problem;
S = (0 x 7) + ( x 9.8 x 7²)
S = 240.1m
