Given the context of this question being quite large and my main problem being the solving i won't bother with diagrams but anyway

the kinematics conditons are

Such that i have 10 = (Vcos15)t + 0.5gt^2
1.9 = (Vsin15)t + 0.5gt^2

Can anyone please show me the steps for solving this simultaneously for V,

Cheers.

Write the 1st eqn as:Vcos15 = whatever
Write the 2nd eqn as :Vsin15 = whichever

Divide the 1st eqn by the 2nd eqn
Solve for t
substitute for t into the 1st or 2nd eqn
Solve for V
