Cоmplete the fоllоwing question on your own pаper аnd uploаd your response via side angle camera. A car is stopped at a traffic light. The light turns green, and at time t = 0 the car starts moving and travels with a constant acceleration. At that instant a truck traveling at constant speed vt is alongside the car, with the front of each vehicle at position x = 0 , as shown above. The truck passes the car, but the car later catches up to the truck in front of a house, such that at time tD the front of each vehicle is at position x = D. 1. Sketch a velocity vs. time graph showing the velocity of both vehicles on the same graph. Make sure to indicate any important velocities or times. 2. Two students are discussing how the speed of the car compares to the speed of the truck when both vehicles are in front of the house. Student 1 says,“The distance traveled by the car and the truck is the same, and the time is the same, so they must have the same speed.” Student 2 says,“I don’t see how that can be. The car catches up to the truck, so the car has to be going faster.” a) Which aspect of Student 1's reasoning, if any, are correct? Support your answer in terms of relevant features from your graph. b) Which aspect of Student 2's reasoning, if any, are correct? Support your answer in terms of relevant features from your graph. 3. Derive an expression for the acceleration of the car in terms of D and vt 4. Determine the time at which the speed of the car is equal to the speed vt of the truck. Express your answer in terms of tD. Justify your answer. Uploading work: CLEARLY SHOW THE METHOD USED AND THE STEPS INVOLVED IN ARRIVING AT YOUR ANSWERS. It is to your advantage to do this, since you may obtain partial credit if you do, and you will receive little or no credit if you do not. Attention should be paid to significant figures. Access the upload option: After finishing your test, go to the last question and select the "record upload media" option; Switch to your webcam: Ensure your webcam is plugged in and switch to its view within the assessment interface; Prepare your environment: Make sure you have good lighting (e.g., a desk lamp or natural light from a window) and maintain an optimal distance of 6-8 inches between your camera and your paper; Record "video pictures": Start recording, immediately hit "finish" after the countdown to take a snapshot of your work, and then save the media; Ensure clarity: Take your time when recording to avoid blurry or mushy images. Do not hold your paper, as this can cause the webcam to shake and result in unclear pictures; Submit multiple images if needed: If your teacher requires more than one picture or images from different sections, you can add additional "video pictures"; Review your submission: Before finalizing, double-check that the images you've provided are clear and make sense; Submit your test: Once all questions are answered and your work is uploaded, scroll to the end of your test and hit submit. Video If there is an issue with submitting your handwritten work via your side-angle camera (or if the images do not look clear), you will close the assessment and immediately upload your work to the "comments" box of the closed assessment.
