Homework Statement
A speedy destroyer’s 5 inch gun fires a projectile at some angle to the horizontal. If the thing travels a distance of 23 500 m in 135 s, what was the projectile’s initial velocity?
Homework Equations
v=vi+at
v^2=vi^2+2a(s) s=displacement
s=vi*t+.5at^2
The Attempt at a Solution
Hello, I really don't know where to start, since I don't have an angle. I've made a diagram and split into 3 parts, up, down, and horizontal. How do I progress through this problem!?
