A ball is thrown vertically upward

A ball is thrown vertically upward with an initial speed of 23 m/s. Then, 1.6 s later, a stone is thrown straight up (from the same initial height as the ball) with an initial speed of 37 m/s .
How far above the release point will the ball and stone pass each other? The acceleration of gravity is 9.8 m/s2 .
Answer in units of m

Set the time when the first ball is launched to be t=0. Set the time they meet to be t=T (assume they will meet).

If both balls meet at t=T, their vertical displacement would be the same.

Therefore ||\Delta y_1=\Delta y_2||, which gives $$V_1T-\frac 12 gT^2=V_2(T-1.6)-\frac12 g(T-1.6)^2$$

Solve for T and then find ||\Delta y||.
