A rock is launched into the air with a velocity of 12.7 m/s at an angle of 32° off the horizontal ground. Which of the following is true? a) The acceleration is 9.8 m/s to the right. b) acceleration is 9.8 m/s to the left. c) acceleration is 9.8 m/s upward. d) The acceleration is 9.8 m/s downward. e) none of the above

From negative to negative

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.
