1. The problem statement, all variables and given/known data Help with projectile motion please? A particle is at an elevation of 1.02m from the floor when it takes off. It reaches a max height of 1.85m above the floor and stops at .930m above the floor. How do you find the time of flight, the take off angle, the initial vertical and horizontal velocity? 2. Relevant equations 3. The attempt at a solution I have no idea how to start this without a given angle. Can someone explain this concept to me?
