Question
please see attached photo.
A car traveling with an Initial velocity of 20 m/s accelerates at a constant rate of 2 m/s2 for a time of 4 seconds. What is its velocity at the end of this time? m/s What distance does the car travel during this process? m A car moves along an east-west road so that its velocity varies with time as shown in the graph below, where west is the positive direction. For each part of this question, indicate which one or more time intervals is correct by entering the corresponding letter or letters. If more than one letter is correct, enter the letters of your answer in alphabetical order with no spaces in between. During which one or more time intervals is the car speeding up? Choose all that apply. During which one or more time intervals is the car at rest? Choose all that apply. During which one or more time intervals is the magnitude of the car's acceleration largest? Choose all that apply. During which one or more time intervals is the car moving east? Choose all that apply.Explanation / Answer
