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
[tex]v=u+gt[/tex]
Where, v = final velocity
u = initial velocity
g = acceleration due to gravity
t = time
Put the value into the formula
[tex]v=0+9.8\times4[/tex]
[tex]v=39.2\ m/s[/tex]
Hence, The final velocity of the ball is 39.2 m/s.
