Kinematics -- projectile motion -- time to maximum height? 1. The problem statement, all variables and given/known data The nozzle of a fire hose discharges water at a speed of 10 m/s. The nozzle is aimed straight up. How long does it take for a water drop to reach its maximum height? Start with translating the question: vi= 10 m/s vf= 0 m/s t=? s a= -9.8 m/s^2 delta−x= ? 2. Relevant equations 3. The attempt at a solution OK, so I'm assuming that solving this takes 2 steps. One entails finding the maximum height, then using a kinematic formula to find time. Is that logic sound?
