A C B Question 4 The diagram above shows a ball rolling on a frictionless track. Assume the ball starts on segment A, rolls down segment B, up segment C before turning around and rolling back to its starting point on segment A. Complete the table below by indicating whether the position, velocity and acceleration of the ball are positive (+), negative (-) or zero (0) as the ball rolls on each segment of the track. Be sure to note the coordinate system shown in the diagram! Position Velocity Acceleration Ball rolls to the left across segment A Ball rolls to the left down segment B Ball rolls to the left up segment C Ball reaches its maximum height on segment C Ball rolls to the right down segment C Ball rolls to the right up segment B Ball rolls to the right across segment A Sketch the velocity vs. time and acceleration vs. time graphs corresponding to this motion.
