i got vy by doing v0sintheta= 26
No. In the formula I gave:
y0 is your initial position, which I presume is on the ground at height = 0
v0 (which I'll change to v0y) is the vertical
component of the initial velocity, what you call v0sin(theta)
g = 9.8 m/s^2
To make it less confusing, I'll relabel v0 to be v0y in my equation.
