The height h(t) and horizontal distance x(t) traveled by a ball thrown at an angle A with a speed v are given

By

 

At Earth's surface the acceleration due to gravity is g = 9.81 m/s2.

a. Suppose the ball is thrown with a velocity v = 10 m/s at an angle of 35°. Use MATLAB to compute how

high the ball will go, how far it will go, and how long it will take to hit the ground.

b. Use the values of v and A given in part a to plot the ball's trajectory; that is, plot h versus x for positive

values of h.

c. Plot the trajectories for v = 10 m/s corresponding to five values of the angle A: 20°, 30°, 45°, 60°, and 70°.

 

d. Plot the trajectories for A = 45° corresponding to five values of the initial velocity v: 10, 12, 14, 16, and 18

m/s.
