Figure P2.55 shows the motion diagram, made at two framesof film per second, of a ball rolling along a track. The track hasa 3.0-m-long sticky section.FIGURE P2.55a. Use the scale to determine the positions of the center of theball. Place your data in a table, similar to Table 2. 1, showingeach position and the instant of time at which it occurred.b. Make a graph of x versus t for the ball. Because you havedata only at certain instants of time, your graph shouldconsist of dots that are not connected together.c. What is the change in the ball's position from t = 0 s toI= I.O s?d. What is the change in the ball's position from t = 2.0 s toI = 4.0 s?e. What is the ball's velocity before reaching the sticky section?f. What is the ball's velocity after passing the sticky section?g. Determine the ball's acceleration on the sticky section of thetrack.
