A dog's motion whilst chasing a frisbee is captured using a motion detector and displayed on the graph shown. Use the graph to answer the following questions. 60 Right is defined as positive. Answers have a 5% tolerance to allow for estimation. 40 Describe the dog's direction of travel: 20 right v time (s) Describe the dog's motion: increasing speed 10 15 20 25 30 -20 What is the distance traveled? m -40 What is the final speed? m/s -60 What is the magnitude of the acceleration? m/s? velocity (m/s)

A bus makes a trip according to the position-time graph shown in the drawing. What is the average velocity (magnitude and direction) of the bus during each of the segments A, B, and C? Express your answers in km/h. The scale for the time axis is 2 h per increment, and scale for the velocity axis is 210 km per increment. (Indicate direction by the sign of the velocity.) segment A segment B segment C km/h km/h km/h Show My Work (Optionall Time (h)

You measure the motion of a dynamics cart using a motion sensor.  You then plot the cart’s position vs. time and velocity vs. time.  The best way of finding the average acceleration of the cart is to find: a. the y-intercept of the position vs. time plot. b. the y-intercept of the velocity vs. time plot. c. the slope of the position vs. time plot d. the slope of the velocity vs. time plot. e. none of the above

Lisa runs 1.5 km along a straight path and then turns and runs 2.4 km in the opposite direction. She then turns back and runs 700 m in the original direction. Let Lisa’s original direction be the positive direction. What are the displacement and distance, in km, she ran? * A. Displacement is 4.6 km, and distance is -0.2 km. B. Displacement is -0.2 km, and distance is 4.6 km. C. Displacement is 4.6 km, and distance is +0.2 km. D. Displacement is +0.2 km, and distance is 4.6 km.

Which of the following statements are true regarding velocity-time graphs?I.     The slope of a velocity-time graph is acceleration.     II.    The graph has a slope of zero if the object is at rest.     III.  A line with negative slope indicates that the object is slowing down.

An object is held 10 m above the ground. It is tossed upward at 5 m/s. Describe the object's motion in words. Write an equation of motion for the object. How long does it take for the object to hit the ground? How far above the ground is the object in 1.5 sec?

I know the answer is c but can you please explain why

As a train accelerates uniformly it passes successive 850 meter marks while traveling at velocities 1.5 m/s and then 15 m/s. a. For the first mark of the journey, what is the acceleration of the train in m/s sq? b. Determine the train's velocity when it passes the next mark in m/s. c. Determine the time it takes to travel the 1.7-km distance in seconds.
