A juggler maintains four balls in vertically upwards motion. He attempts next ball after `(1)/(4)` seconds. For the show to go one, what should be the height for which he thrwos the ball ? `(g = 10 m//s^(2))`

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)

A ball is thrown vertically upwards from the top of a tower with a velocity of 10m/s. If the ball falls on the ground after 5 seconds, the height of the tower will be? (use g=10m/ s^(2) )

A ball thrown vertically upwards returns to the thrower in 20 second. Calculate the velocity with which it was thrown and the maximum height attained by the ball. Take g = 10 m//s^(2) .

A juggler maintains four balls in motion, making each to them to rise a height of 20 m from his hand. What time interval should he maintain, for the alphaer distance between them.

a man in a balloon rising vertically with an acceleration of 4.9 m/s^2 releases a ball 2 seconds after the balloon is let go from the ground. The greatest height above the ground reached by the ball is

A ball is thrown downwards with a speed of 20 m s^(-1) , from the top of a building 150 m high and simultaneously another ball is thrown vertically upwards with a speed of 30 m s^(-1) from the foot to the building . Find the time after which both the balls will meet. (g=10 m s^(-2)) .

A man is throwing balls in air. He throws next ball when previous one is at the highest point. If he throws each ball after 2s , then height to which ball rises is

A ball is thrown vertically upward attains a maximum height of 45 m. The time after which velocity of the ball become equal to half the velocity of projection ? (use g = 10 m//s^(2) )
