A man throws balls with the same speed vertically upwards one after the other at an interval of 2s. What should be the speed of the throw so that more than two balls are in the sky at any time ? (Given `g = 9.8 m//s^(2)`)

A man throws balls with same speed vertically upwards one after the other at an interval of 3s. What should be the speed of throw so that more than two balls are in the sky at any time?

A man throws balls with the same speed vertically upwards one after the other at an interval of 2 second. What should be the speed of the throw so that two balls are in the sky at any time?

A man throws ball with the same speed vertically upwards one after the other at an interval of 2 seconds. What should be the speed of the throw so that more than two ball are in the sky at any time (Given g=10(m)/(2^2) )

A man throws ball with the same speed vertically upwards one after the other at an interval of 2 seconds. What should be the speed of the throw so that more than two ball are in the sky at any time (Given g=10(m)/(2^2) )

A man throws balls with the same speed vertically upwards one after another at an interval of 2 seconds. What should be the speed so that more than two balls are in the sky at any time? ( g = 9.8ms^-2 )

A person throws balls upward in regular intervals of time of 2 s. What should be the speed of throwing of balls such that both balls remain in air ?

A person throws balls upward in regular intervals of time of 2 s. What should be the speed of throwing of balls such that both balls remain in air ?

A boy is standing on top of a tower of height 85 m and throws a ball in the vertically upward direction with a certain speed. If 5.25 seconds later he hears the ball hitting the ground, then the speed with which the boy threw the ball is (take g = 10 m/s^(2) , speed of sound in air = 340 m/s)

Two balls are projected vertically upward with same speed 35 m/s in 3s interval. Find height at which both balls collide.
