Chapter 14.3, Problem 53E

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.

49. A baseball is hit 3 ft above home plate with an initial velocity of 〈60, 80, 80〉 ft/s. The spin on the baseball produces a horizontal acceleration of the ball of 10 ft/s² in the eastward direction.
