Answer:

The final velocity of the ball is 39.2 m/s.

Explanation:

Given that,

A ball is dropped from rest from a high window of a tall building.

Time = 4 sec

We need to calculate the final velocity of the ball

Using equation if motion

v=u+gt

Where, v = final velocity

u = initial velocity

g = acceleration due to gravity

t = time

Put the value into the formula

v=0+9.8\times4

v=39.2\ m/s

Hence, The final velocity of the ball is 39.2 m/s.
