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
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
So the velocity of the ball when its hit the ground will be 54.22 m/sec
