Problem 4: A projectile is fired with an initial velocity of 54.1 m/s, at an initial inclination of 33.7 degrees with the horizontal r-axis. All initial variables (displacement and time) start at 0. You are asked to consider two cases of motion for the projectile, one without drag, and one with drag, with both the cases including effects of gravity. a) For motion with no drag, acceleration vector is given as а -g, where g 9.8 m/s. b) For motion...
