A CD spins at a constant angular velocity of 5.0 revolutions per second counterclockwise. Which of the following statements about the CD is true? A. A net torque acts on it clockwise to keep it moving.
B. A net torque acts on it counterclockwise to keep it moving.
C. No net torque acts on it at all.

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.

There are no answer choices, so an example would be: it takes a long time and a lot of precision to sew a shirt by hand, so a machine was created to do the job instead.
