Answer:

The time is 4 sec.

Explanation:

Given that,

Distance = 78.4 m

We need to calculate the time

Using equation of motion


s=ut+(1)/(2)gt^2


t =\sqrt{(2s)/(g)}

Where, s = distance

g = acceleration due to gravity

t = time


t =\sqrt{(2*78.4)/(9.8)}


t=4\ sec

Hence, The time is 4 sec.
