Answer:
11.1s
Explanation:
Given parameters:
Height of cliff = 600m
Unknown:
How long it takes to hit the ground = ?
Solution:
To solve this problem, we use one of the kinematics equation;
H = ut + [tex]\frac{1}{2}[/tex]gt²
H is the height
u is the initial velocity = 0m/s
t is the time taken
g is the acceleration due to gravity
600 = [tex]\frac{1}{2}[/tex] x 9.8 x t²
600 = 4.9t²
t² = 122.5
t = 11.1s
