The height and speed of a projectile (such as a thrown ball) launched with a speed of υ₀ at an angle A to the horizontal are given by

 

where g is the acceleration due to gravity. The projectile will strike the ground when h(t) = 0, which gives the time to hit t_hit = 2(υ₀/g)sinA.

Use the switch structure to write a MATLAB program to compute the maximum height reached by the projectile, the total horizontal distance traveled, or the time to hit. The program should accept as input the user’s choice of which quantity to compute and the values of υ₀, A, and g. Test the program for the case where υ₀ = m/s, A = 30°, and g = 9.81 m/s².
