Homework Statement
A man acts as as a human cannonball. When the cannon is fired, he has a velocity of 18ft/s. How far will the man have traveled when his acceleration is 0? When will this occur? Neglect friction.
Also given is:
Man is 120 lb-m
Homework Equations
kinematics equations:
v = v0 + a*t
x - x0 = Vo*t + 1/2 a*t^2
v^2 = Vo^2 + 2a (x - X0)
x - x0 = 1/2 (v0 + v) t
x - x0 = v*t - 1/2 a*t^2
The Attempt at a Solution
Im thinking about maybe using one of the equations without t to find the final x, and then use the final x to find t. Is that correct? Any help?
