A person throws balls into the air one after the other at an interval of one second. The next ball is thrown when the velocity of the ball thrown earlier is zero. To what height does each ball rise?

Options:

Answer:

Solution:

The velocity becomes zero $1$ s after each throw, so $0 = u - 10 (1)$ gives $u = 10$ m/s. Then $0 = u^{2} - 2 g h$ gives $h = \frac{100}{20} = 5$ m. Option A.
