Two identical balls are shot upward one after another at an interval of 2s along the same vertical line with same initial velocity of `40 ms^-1`. The height at which the balls collide is

Two balls of equal masses are thrown along the same vertical direction at an interval of 2 seconds , with the same initial velocity of 1 45 ms^(-1) . Then these balls collide at a height of (use g=10 ms^(-2)

Two balls of equal masses are thrown upwards, along the same vertical direction at an interval of 2 seconds, with the same initial velocity of 40m//s . Then these collide at a height of (Take g=10m//s^(2) ).
