q15

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 (250,250,0). 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 t2 0.
b. Make a sketch of the trajectory.
c. Determine the time of flight and range of the bullet.
d. Determine the maximum height of the bullet.
.....
a. The velocity vector is v(t) =
