As shown in Figure 2.9, Whipple chose a coordinate system that was different from Cralls. There are many possible coordinate systems that can be used to analyze the motion of the cart. For example, a third student (Yoon) chose to place the origin of her coordinate system at position A (the) carts initial position) and use a southward-pointing y axis as her positive axis. a. Use the distance information given in Table 2.2 to make a new table that gives the carts position at each of the 16 times according to Yoons coordinate system. Hint: A sketch similar to Figure 2.9 is a good place to start. b. Use the data in your table to make a new position-versus-time graph. Hint: CHECK and THINK about your graph by comparing it with Figure 2.6.
Based on a grade 11 physics student, answer the following question: The position-time graph below represents the motion of two speed skaters, Bill and Ted on their Excellent Adventure as they time travel back to the 1952 winter Olympics in Oslo. a) What was Ted’s acceleration through the race? (assume constant) b) Make a velocity-time graph of Bill & Ted’s Speed Skating race.
A diagram representing the motion of two cars is shown below. The number neareach dot indicates the clock reading in seconds when the car passes that location.(a) Indicate times when the cars have the same speed. (b) Indicate times whenthey have the same position. Explain your reasoning.
Explain why we only consider one dimensional motion when using a single motion sensor. Based on the definition of velocity, describe what you should observe in the velocity vs. time graph if you were measuring a stationary, distant object and you suddenly slid and object into the beam from the side [hint: think about the behavior of the position graph in this case.]
Match the given velocity vs time graph to the correct position vs time graph that represents the same motion. Don’t worry about matching exact times, just look for the right pattern.In a couple sentences or bullet points, describe a physical scenario for the motion (for example, using the motion of a person walking or a car driving).
Haley is driving down a straight highway at 67 mph. A construction sign warns that the speed limit will drop to 55 mph in 0.50 mi. What constant acceleration (in m/s2) will bring Haley to this lower speed in the distance available? Express your answer in meters per second squared.
You are an observer on the ground. (a) Draw two motion diagrams representingthe motions of two runners moving at the same constant speeds in oppositedirections toward you. Runner 1, coming from the east, reaches you in 5 s, andrunner 2 reaches you in 3 s. (b) draw a motion diagram for runner 2 as seen byrunner 1. Explain your work.
Based on a grade 11 physics student, answer the following question: The position-time graph below represents the motion of two speed skaters, Bill and Ted on their Excellent Adventure as they time travel back to the 1952 winter Olympics in Oslo. What was Ted’s velocity at 20s? What was Bill’s velocity during the middle portion of the race? What was Ted’s average velocity throughout the race? What was Ted’s acceleration through the race? (assume constant) Make a velocity-time graph of Bill & Ted’s Speed Skating race.
Chris is holding two softballs while standing on a balcony. She throws ball 1 straight up in the air and, at the same instant, releases her grip on ball 2, letting it drop over the side of the building. Which velocity graph given is best represents the motion of the two balls?
In a total time of 3.0 minutes, a duck on a pond paddles 31 m [N33oE] and then paddlesanother 57 m [E28oS]. Solve for the displacement graphically (with a ruler andprotractor) and then answer the questions. Using the displacement you determined from your graph, what was the duck’s average velocityfor the trip? What total distance did the duck travel? What was the average speed of the duck for the whole trip?
