a man throws ball with the same speed vertically upward one after the other at an interval of 2 seconds.what should be the speed of the throws so that more than two balls are in the sky at any time?

Answered by admin @ 20/08/2021

When you throw the ball upwards the final velocity becomes zero therfore,
v=u+at
0= u-gt
u= 10×2=20 m/s
Hence, when you throw a ball with minimum 20m/s in a time interval of two seconds two balls can be in air simulataneously....
