Chapter 15.3, Problem 6cTH
Carts A and B move along a horizontal track. The strobe diagram shows the locations of the carts at instant 1−5, separated by equal time intervals.
-
c. During a small time interval from just before instant 2 until just after instant 2, does the distance between cart A and cart B
increase, decrease, or
remain the same? Explain.
Consider the following response to the above question:
“For the small interval containing instant 2 cart B is ahead and speeding up, so the distance between the carts must be increasing.”
Do you agree or disagree? Explain.

A student has assembled an arrangement of tracks on which a steel ball has the motion represented by the v versus t graph at the right. The ball is released from rest (v = 0 cm/s) at x = 46 cm when t = 0 s.
a. At what time (to the nearest second) was the ball at x = 188 cm? Show your work, explaining how you determined your answer from the v versus t graph.
b. What was the magnitude of the average velocity of the ball over the entire time interval shown on the graph (i.e., between t = 0 s and t = 20 s)? Show all work.
Two identical objects, A and B, move along straight, parallel, horizontal tracks. The graph above represents the position as a function of time for the two objects.
A. At a time of 2 seconds, where the lines intersect, do the displacements of the two objects from their initial positions have the same magnitude? Briefly explain your answer.
B. At a time of 2 seconds, where the lines intersect, do the velocities of the two objects have the same magnitude? Briefly explain your answer.
C. At a time of 2 seconds, where the lines intersect, which object, if either, has a net force with a greater magnitude exerted on it? If the net force has the same magnitude for both objects, indicate this explicitly.
D. In a clear, coherent paragraph-length response, explain your response to part (c). Be sure to reference and compare the graphed information for both objects A and B.
Two cars, P and Q, travel in the same direction on a long, straight section of a highway. Car P passes car Q at time to.
1) Suppose cars, P and Q each move with constant speed. At time to, is the magnitude of the instantaneous velocity of car P greater than, less than, or equal to the magnitude of the instantaneous velocity of car Q? Explain.
2) Suppose instead that car P is moving with constant speed but car Q is speeding up. At time to, is the magnitude of the instantaneous velocity of car P greater than, less than, or equal to the magnitude of the instantaeous velocity of car Q? Explain.

Ship A is traveling south at the rate of 2 km/hr, at the instant that ship B, which is 32miles south of ship A, is traveling east at a rate of 4 km/hr. a) Are they separating or approaching at the end of 2 hrs, and at what rate? b) At what time are they nearest together?c) What is their minimum distance apart?arrow_forwardFor part b, I do not really understand what the question is asking. During the 200 m trip upwards, to we have to consider that the elevator accelerates for 5 seconds, then decelarates for 5 secs and then moves with constant velocity? I do get the final answer that is 45 secs, but Ido not conceptually understand how I am supposed to understand that there is a period of decelaration during the upward motion. Could you please solve only part b and help me understand why both periods of acceleration and deceleration both need to be taken into consideration?arrow_forwardAn ant is crawling along a straight wire, which we shall call the x axis, from A to B to C to D (which overlaps A), as shown in the figure below.
