1. The problem statement, all variables and given/known data 2. Relevant equations 3. The attempt at a solution Maximum height attained by first projectile H = u2sin2θ/2g = 15m If acceleration vector is assumed a = axi+ayj , then at H √(ax2+ay2) = 50 . Now I need to use the given conditions to come up with another equation . Not sure how to proceed . Please help me with the problem .
