1. The problem statement, all variables and given/known data A small dense ball with mass 1.5 kg is thrown with initial velocity <5,8,0> m/s at time t= 0 from the origin (<0,0,0> m) Air resistance is negligible. When the ball reaches its maximum height, what is its velocity? 2. Relevant equations Momentum Principle Average Velocity 3. The attempt at a solution Though I have an idea of how to approach some of the questions regarding this problem, I have not been able to understand the following: How do I know what the maximum height the ball reached is?
