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 + [tex]\frac{1}{2}[/tex] 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) + ( [tex]\frac{1}{2}[/tex]  x 9.8 x 7²)

     S = 240.1m
