A man is standing on top of a building $100m$ high. He throws two balls vertically, one at $t = 0$ and other after a time interval $($less than $2$ seconds$)$. The later ball is thrown at a velocity of half the first. The vertical gap between first and second ball is $+15m$ at $t = 2s$. The gap is found to remain constant. Calculate the velocity with which the balls were thrown and the exact time interval between their throw.
