THE VERTICAL DISPLACEMENT IS
NOT ZERO BECAUSE THE PROJECTILE LANDS ON HEIGHT H
Problem 1: Consider a projectile launched with an initial velocity of 120 f/s. Let us assume that the projectile lands on a a) Determine the range R as a function of time. b) Determine the initial launch angle, 8, such that the projectile achieves the maximum possible horizontal range Hint: think about how to compute maxima and minima from calculus. Once you have computed the launch angle...

Dr. C. #1: Exploding Projectile: A projectile of mass 9.6 kg is shot from the ground with an initial velocity of 12.4 m/s at an angle of 54° above the horizontal. A. Assuming the ground underneath the projectile's path is flat, what is the maximum height h the projectile reaches, its horizontal range R, and the time it spends in the air? Suppose that, at the peak of the projectile's motion, an explosion splits the projectile in half and one...
