Use the model for projectile motion, assuming there is no air resistance. [a(t) = 32 feet per second per second or a(t) = -9.8 meters per second per second]

Use a graphing utility to graph the paths of a projectile for V₀ = 20 meters per second, h = 0 and 

(a) θ = 30°

(b) θ = 45°

(c) θ = 60° 

Use the graphs to approximate the maximum height and range of the projectile for each case.
