Just calculate the individual distances and sum them for the total distance: d = 45/60 * 55 + 16/60 * 95 + 55/60 * 50 km Then calculate the total time t (3 trip times plus 30 min). Average speed = d/t

Speed vertically of 24m/sec will take a height of (v^2/2g) = 29.388 metres to attain. The v^2 is 24^2, not 15^2, and g used is 9.8.

Vx = 19.1*cos(33.4) = 15.95 m/s flight time T = 29.2m / 15.95m/s = 1.83s Vyi = 19.1*sin(33.4) = 10.51 m/s Vy = Vyi - g*T = 10.51 - 17.95 = -7.44 m/s (going down) speed = sqrt(Vx^2 + Vy^2) = 17.6 m/s

From your problem statement it sounds like you're only interested in the vertical dimension, and you also need to neglect the effect of aerodynamic drag. With these assumptions, right before the ball hits the ground it has converted...
