Homework Statement
Two projectiles are launched from the ground with initial speeds of 100 meters per second. One is launched straight up, the other at a 30-degree angle. How much time elapses between each's return to ground level?
Theta = 30
g = 10 m/s
Vinitial = 100
Homework Equations
y = vt - 1/2gt^2
The Attempt at a Solution
As you can see in the image, I attempted to use the equations that I THINK were correct for this problem. My professor just threw a bunch of equations up on the board, some of which he said we don't need for now and they're just there to be there...so, hopefully I did these right.
