Answer:
The velocity of the ball when its hit the ground will be 54.22 m/sec
Explanation:
We have given height from which ball is dropped h = 150 m
Acceleration due to gravity [tex]g=9.8m/sec^2[/tex]
As the ball is dropped so initial velocity will be zero so u = 0 m/sec
According to third equation of motion we know that [tex]v^2=u^2+2gh[/tex]
[tex]v^2=0^2+2\times 9.8\times 150[/tex]
[tex]v=54.22m/sec[/tex]
So the velocity of the ball when its hit the ground will be 54.22 m/sec
