Use the model for projectile motion, assuming there is no air resistance. Find the vector-valued function for the path of a projectile launched at a height of 10 feet above the ground with an initial velocity of 72 feet per second and at an angle of 30° above the horizontal. r(t) - Use a graphing utility to graph the path of the projectile. r(t) r(t) 20 50 100 150 200 250 300 50 100 150 200 250 300 r(t) r(t) 50 100 150 200 250 300 50 100 150 200 250 300
