s = 1.0 m 0= 15° h = 1.2 m 10. I set up my inclined track apparatus at an angle of 15° on a lab bench as shown in the figure above. I then release a billiard ball from rest and let it roll down the track. The distance the ball rolls down the track is 1.0 m and the vertical distance it falls to the floor after leaving the track is 1.2 m. What is the total horizontal distance the ball travels from the point where I release the ball to the point where it hits the floor?
