1.	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. 3 sB. `(3)/(2) s`C. 1 sD. 2 s
Answer» Correct Answer - C From `v^2 = u^2 - 2 as` we have `0 = u^2 - 2(10)(20)` or `u = 20 m//s` Also `v = u - at` or `0 = 20 - 10 t` or `t = 20 s` So, the ball returns to the hand of the juggler after `4 s`. To maintain alphaer distance, the balls must be thrown up at an interval of `(4)/(4)` or `1 s`.
