For #1  I think the 7,5 and 4,5 and 0,15 are really 7.5 and 4.5 and 0.15

So, the equation that will solve for t1 looks like the following

gt1^2/2 + 7.5 = g(t1 + 0.15)^2/2 + 4.5   With this you will get a quadratic equation equal to 0 and then you can solve for the roots to solve for t1.

For #2 it's the same idea

gt1^2/2 + 1.2 = g(t1 + 0.12)^2/2
