1. The problem statement, all variables and given/known data 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 2. Relevant 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 3. 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?
