A very large number of balls are thrown vertically upwards in quick successions in such a way that the next ball is thrown when the previous one is at the maximum height. If the maximum height is 5m, then number of balls thrown per minute is (take g=10m//s^(2) )

In quick succession, a large number of balls are throun up vertically in such a way that the next ball is thrown up when the previous ball is at the maximum height. If the maximum height is 5 m , then find the mumber of the thrown up per second (g=10 m s^(-2)).
