Consider the motion of a bullet that is fired from a rifle 6 m above the ground in a northeast direction. The initial velocity of the bullet is (200, 200, 0) . Assume the x-axis points east, the y-axis points north, the positive z-axis is vertical (opposite g), the ground is horizontal, and only the gravitational force acts on the object.
a. Find the velocity and position vectors for t >_0.
