Textbook Question
Chapter 2, Problem 93TDI
Two balls, A and B, are released simultaneously from rest at the left end of the equal-length tracks, as shown.
(a) Which ball will reach the end of its track first?
(b) Does ball B roll faster along the lower part of track B than ball A rolls along track A?
(c) Is the speed gained by ball B going down the extra dip the same as the speed it loses going up near the right-hand end? Does this mean that the speeds of balls A and B will be the same at the ends of the tracks?
(d) So, overall, does ball A or ball B have the greater average speed? (Do you wish to change your answer to (a)?

I set up my inclined track apparatus at an angle of 15 degrees 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?
Mr. M is now racing on a track that looks like this. He laps around this track in such a way that his car travels in circles represented by the dotted line. If the fastest his car can go around the track without any friction is 34.0 m/s, what distance ‘d’ (in the diagram) should he race his car at?
A 4 m ladder leans against a wall. The bottom of the ladder is 1.7 m from the wall at time t = 0 sec and slides away from the
