Study the dot diagram below. Which verbal description matches the car's motion? The car slowsly accelerates from rest. Then, the car remains at rest for several seconds. Finally, the car moves with a constant leftward velocity. The car moves in the leftward direction and a rightward acceleration. The car movs with a rightward velocity and a rightward acceleration. The car moves with a constant, leftward velocity. Then, the car remains at rest for several seconds. Finally, the car moves with righward acceleration. The car moves with a rightward acceleration. Then, the car remains at rest for several seconds. Finally, the car moves with a low constant speed. The car moves at constant speed. Then, the car remains at rest for several seconds. Finally, the car moves with a constant leftward velocity.

not changing Learning Goal: To understand the distinction between velocity and acceleration with the use of motion diagrams. Previous Answers In common usage, velocity and acceleration both can imply having considerable speed. In physics, they are sharply defined concepts that are not at all synonymous. Distinguishing clearly between them is a prerequisite to understanding motion. Moreover, an easy way to study motion is to draw a motion diagram, in which the position of the object in motion is sketched at several equally spaced instants of time, and these sketches (or napshots) are combined into one single picture. Correct While the ball is in free fall, the magnitude of its velocity is increasing, so the ball is accelerating. Part B In this problem, we make use of these concepts to study the motion of a power ball. This discussion assumes that we have already agreed on a coordinate system from which to measure the position r (t) (also called the Since the length of v is directly…

A swimmer pushes off a wall from rest where she has a constant acceleration of 2m/s2 for 1.5 seconds. She then continues for 10 seconds at constant velocity. At this point, a) How far away from the wall is she if the pool is 50m? b) If she then glides to a stop, what was her deceleration rate? c) Draw the position verse time graph, velocity verse time graph, and acceleration verse time graph. You can assume all accelerations are constant. d) Now take your velocity verse time graph and re calculate the distance covered by the swimmer.

1.The motion of an athletic mouse is shown in the graph below. Use the graph to answer the following questions. (a) Total distance travelled. (b) Total displacement (c) Average speed (d) Average velocity 2. Sketch the corresponding velocity-time graph for the given position time graph. Make sure to CLEARLY indicate values for key points on the graph.

Mike is at rest.  Glen is driving towards him at a speed of 15 m/s.  Mike starts accelerating at a constant acceleration of 3 m/s^2, 1 second after Glen passes him.  What is Mike's displacement when he passes Glen?  What is Mike's velocity at the instant he passes Glen?  Draw a position vs time graph and a velocity vs. time graph for both vehicles. How does Mike's average velocity during the pursuit compare to Glen's constant velocity?

A coin that is tossed straight up into the air. After it is released, it moves upward, reaches its highest point and falls back down again. Use one of the following choices (A through G) to indicate the acceleration of the coin during each of the stages of the coin's motion described below. Take up to be the positive direction. Answer choice J if you think that none is correct. A. The acceleration is in the negative direction and constant. B. The acceleration is in the negative direction and increasing. C. The acceleration is in the negative direction and decreasing. D. The acceleration is zero. E. The acceleration is in the positive direction and constant. F. The acceleration is in the positive direction and increasing. G. The acceleration is in the positive direction and decreasing. The coin is mo downward. OE OF OJ O C O A OD OG O B

Please view the pictures below to answer the following questions. Match the following descriptions of an objects motion with the graph of the object's position vs time graph shown in the pictures.  Question 1: An object has a postive initial velocity and a negative accelertion, but never comes to a stop.  Question 2: An object has an initial negative velocity and a positive acceleration which slows it to a stop before speeding it up in the positive direction.  Question 3. An object is initially at rest and then accelerates in the negative direction.  Question 4: An object has a postive constant velocity    Please answer questions 1-4

In each table below, the motion is described by a position (x)-vs-time graph, a velocity (v)-vs-time graph, a verbal description or a motion map. The other three representations have been left blank. Complete the missing representations. Be sure to include each of the following in your verbal description: starting position, direction moved, type of motion, relative speed.

Please help with question 3. Thank you.

Karen bikes at 8 mph for 0.3 hours from home to the park. At soon as she arrives, Karen remembers she has a study session with Marie. So, Karen turns around and bikes to Marie's house at 12 mph for 0.1 hours. They study for 0.5 hours. Then, Karen bikes home for 0.4 hours. Note: Marie's house is in between Karen's house and the park. 1. Plot a velocity vs. time graph. 2. Calculate Karen's speed when she bikes from Marie's to her house. 3. Calculate the distance of each segment. 4. Plot a position vs. time graph.
