a stone is allowed to fall from the top of a tower of height 200m and at the same time an another stone is projected vertically upwards from the ground with a velocity of 50 metre per second calculate where and when the two stones will meet. ( take g = 10 metre per second square)

Expert Answer:

The time taken by the body sent upward to meet the top body
is 200/50 = 4 seconds.
The acceleration produced each second to the top body which is dropped is also a deceleration produced to the velocity of stone thrown upward. 
4.9 x 4 x 4 = 78.4 m 
From the top 200 - 78.4 = 121.6 m 
Thus, 
Both stones meet at 121.6 m
