Three-dimensional motion Consider the motion of the following objects. Assume the x-axis points east, the y-axis points north, the positive z-axis is vertical and opposite g, the ground is horizontal, and only the gravitational force acts on the object unless otherwise stated. a. Find the velocity and position vectors , for t ≥ 0. b. Make a sketch of the trajectory. c. Determine the time of flight and range of the object. d. Determine the maximum height of the object. 48. A golf ball is hit east down a fairway with an initial velocity of 〈50, 0, 30〉 m/s. A crosswind blowing to the south produces an acceleration of the ball of −0.8 m/s 2 .
