1. The problem statement, all variables and given/known data The speed of a projectile when it reaches its maximum height is 1/4 the speed when the projectile is at 1/4 its maximum height. What is the initial projection angle? Answer in units of ◦ 2. Relevant equations v2 = v02 + 2a(delta s) 4Vx = v1/4 3. The attempt at a solution I've tried substituting v1/4 for 4vx and some other things, but I lost those papers.
