Position 0 Time (s) 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 approximately which time or times, if any, are the objects moving at the same speed? L the objects are never moving with the same speed during the interval shown, indicate this explicitly. Briefly explain your answer. (b) Describe what is happening to the positions of objects A and B between 3 seconds and 4 seconds. (c) Which object, if either, has an acceleration with a greater magnitude during the time interv shown in the graph? If the accelerations have 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.

Please help I have having trouble telling the difference between instantaneous velocity vs acceleration

Two students, student 1 and student 2, are discussing the graph shown above, which shows the vertical component of the velocity of the box from when it leaves the ramp to immediately before it hits the floor. The students make the following statements. Student 1: This graph shows that the vertical acceleration of the box is constant, and that the box’s speed decreases for the entire time shown. Student 2: The area between the graph and the time axis is the box’s vertical displacement, but the graph is incorrect because the positive displacement should be equal to the negative displacement. The angle of the ramp is changed such that it is larger than θ but less than 90 degrees, while the height of the end of the ramp remains the same. (h) How would the maximum height of the box compare to the original scenario in which the ramp angle was equal to θ ? Justify your ans

Relate the two objects (A and B) that start at x = 0 at t =0 and move in one dimension independently of one another. The graphs of the velocity of each object vs. time are shown below.a.) Which object is farthest from the origin at t = 6s and b.) Which moves with constant non-zero acceleration?

The DETECTOR IS AT THE ORIGIN (position of 0). Choose the statements that accurately describe the motion of the car f GRAPH T At the end the cart is moving with constant speed. 10:At the end the cart is at rest. U Initially the cart moves away from the detector. As the cart is moving, its speed increases. position O Initially the cart moves toward the detector. As the cart is moving, its speed decreases.
