Questions 1. In part I, how does horizontal distance of the projectile vary with initial speed? 2. In part II, how does horizontal distance of the projectile vary with initial height? 3. In part III, how does horizontal distance of the projectile vary with angle of projection and elapsed time? 4. In part III, when the ball is at the highest point of its flight, Answer A) its speed and acceleration are both zero. B) its speed is zero but its acceleration is nonzero. C) its speed is ponzero but its acceleration is zero. D) its speed and acceleration are both nonzero. (you may repeat the simulation if you wish)
