Given :
A tourist drops (from rest) a ping pong ball from the top of the tower, which has a height of 174 meters.
To Find :
How long does it take for the ping pong ball to hit the ground ?
Solution :
We know, equation of motion of object doing free fall is :
....1)
Here, g = 9.8 m/s² ( acceleration due to gravity )
Also, u = 0 m/s ( its free fall )
Putting these values in equation 1), we get :
Therefore, ball will take 5.96 s to hit the ground.
200 meters per minutes
500 meters -300 meters= 200 meters
300 meters -100 meters =200 meters
