A stone is thrown upwards with a velocity `50 ms^-1`. Another stone is simultaneously thrown downwards from the same location with a velocity `50 ms^-1`. When the first stone is at the highest point, the velocity of the second stone is `("Take" g = 10^-2)` :A. ZeroB. `50 ms^-1`C. `100 ms^-1`D. `150 ms^-1`

Answer» Correct Answer - C
`t = (50)/(g) = (50)/(10) = 5 s`
`v = -50 - 10 xx 5 = -100 m//s`.
