The height h(t) and horizontal distance s(t) traveled by a ball thrown at an angle q, with initial speed u, is given a

The acceleration due to gravity is g = 9.81 m/sec.²

Plot the trajectories for the same value of u, but with different angles q: 20°, 30°, 45°, 60°, and 70°. Now find out for what angle the ball travels the highest? Mark this trajectory with bold faced line in your plot.
