1. The problem statement, all variables and given/known data Vy - 15m Vx - 40m U - 17m/s V - 0 Time to reach highest point (t) 1.7s 2. Relevant equations cos 0 = a/c 3. The attempt at a solution 72 degrees. Not sure if this is the correct method of calculating the angle, especially since a projectile's trajectory is a parabola.
