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.
-
d. Is there any time interval during which cart A and can B have the same average velocity? If so, identify the interval(s) and explain. If not, explain why not.
Is there any instant at which cart A and cart B have the same instantaneous velocity? If so, identify the instant(s) (e.g., “at instant 1” or “at an Instant between 2 and 3”) and explain. If not, explain why not.

- Figure P4.8 shows the motion diagram of two balls. The time interval between images is 0.036 s. Each ball starts at point i. The ball on the left is released and falls straight down. At the same time, the ball on the right is launched horizontally and follows the path shown. a. Write the velocity and acceleration of each ball as a function of time. b. What is the velocity and acceleration of each ball at i, G, and K? c. Compare your answers for the two balls in part (b). What similarities do you notice?

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.arrow_forwarda.) Draw the distance vs. time graph. Find the slope. b.) Describe the graph line. What does it imply? a.) Draw the speed vs. time graph. Find the slope. Describe the graph line. What does it imply? b.) Find the slope of the graph and compare it with the calculated acceleration. Describe the motion of a freely falling body based on the results obtained. If, by some suitable mechanism, the falling body had been given an initial downward push instead of being just released, would the resulting value of `g’ have been different? Explain.

With what velocity does it hit the ground? A car starting from rest is accelerated 15 m/s2. In how many seconds will its velocity be equal to 100 m/s? How far will it have traveled during this same time?arrow_forward
- A soccer ball moves in a straight line (the x-axis). The graph in the figure (Figure 1) shows this ball's velocity as a function of time. Submit Request Answer Part C Suppose that the ball moved in such a way that the graph segment after 2.0 s was -3.0 m/s instead of +3.0 m/s. Find the ball's and average velocity during the first 2.5 s in this case. Express your answer using two significant figures. ΑΣφ 画1 ?

Your function should be a function of time (i.e. the t variable should be left as an independent variable) but all other values should be filled in with numbers. Based on your answer above, what type of curve would you expect the position vs. time function to obey? i.A constant (horizontal) curve? ii.A linear curve? iii.A quadratic (parabolic) curve? iv.Another type of curve, such as cubic, exponential, sine, square root, etc...?
