The time is 0.90 sec.
Explanation:
Given that,
Height = 4.00 m
We need to calculate the time
Using equation of motion
For free fall, u = 0
Where, s = distance
g = acceleration due to gravity
t = time
Put the value into the formula
Hence, The time is 0.90 sec.
If a constant force is applied on a body, the body moves with constant acceleration.
