44. A pyrotechnic rocket is fired from a platform 2 ft high at an angle of 60° from the horizontal with an initial speed of 72 ft/sec. Choose a coordinate system with the origin at ground level directly below the launch position. a. Write parametric equations that model the path of the chell as a function of the time t (in sec) after launch. b. Approximate the time required for the shell to hit the oround. Round to the nearest hundredth of a second. c. Approximate the horizontal distance that the shell travels before it hits the ground. Round to the nearest foot.
