1. The problem statement, all variables and given/known data A projectile launched at A with an initial velocity of 24 m/s at the angle θ=60deg, impacts the vertical wall at B. Neglecting air resistance, calculate the height h 2. Relevant equations 3. The attempt at a solution Here is my solution As you can see to find height h I assumed that ##v_y=0## in the second of Eqs. (f) and solved for time. Is this correct or should I have solved first equation of (g) to find time and then solve for y?
