Figure 5.13 shows the velocity of a particle, in cm/sec, along a number line for time −3 ≤ t ≤ 3. (a) Describe the motion in words: Is the particle changing direction or always moving in the same direction? Is the particle speeding up or slowing down? (b) Make over and underestimates of the distance traveled for −3 ≤ t ≤ 3. Figure 5.13

Here's a graph of the velocity (in ft/sec) of an object moving along a horizontal line. (a) Over the interval 0 ≤ t ≤ 24, determine the intervals when the object is speeding up and the intervals when the object is slowing down. (b) From the end of Section 5.1 of the textbook, distance traveled is the area under the velocity vs. time graph. Use this to compute the distance traveled by the object from t = 0 to t = 8 seconds, in feet. (c) Compute the distance traveled by the object from t = 8 to t = 20 seconds, in feet.

The figure shows the velocity of an object for 0 ≤ t ≤ 24. Calculate the following estimates of the distance the object travels between t = 0 and t = 24, and indicate whether each result is an upper or lower estimate of the distance traveled. (a) A left sum with n = 2 subdivisions NOTE: Enter units that match those on the graph. The distance traveled is estimated to be This is (b) A right sum with n = 2 subdivisions. NOTE: Enter units that match those on the graph. The distance traveled is estimated to be This is
