From the top of a 45 m tower one stone is thrown vertically up at $10 m / s$ and another is thrown vertically down at $10 m / s$ . Taking $g = 10 m / s^{2}$ , the ratio of their speeds on hitting the ground is:

Options:

Answer:

Solution:

For each stone $v^{2} = u^{2} + 2 g h = 100 + 900 = 1000$ , so both land with the same speed and the ratio is $1 : 1$ . Option C.
