JEE Main Physics question
In quick succession, a large number of balls are thrown up vertically in such a way that the next ball is thrown up when the previous one is at the maximum height. If the maximum height is 5 m, then find the number of balls thrown up per second (g = 10 ms).
Answer: 1 ball per second
Solution
ms. Time to reach max height s. Since a new ball is thrown every 1 s, ball/s.
