(1) Observer S (at x 0) sees a flash of red light at XR 1200 m from her position and a flash of blue light at x,-480 m on the same straight line. She measures the time interval between the flashes to be 5 us, with the blue flash occurring first (that is, ted ue 5 Hs.) What is the...

With the same condition as in previous problem, what is the average velocity in time interval 0 to 20 s? Yet still for the same setting, what is the average speed in time interval 0 to 20 s? The answer for the average speed is...

Thank you 1. Explain why the average velocity found in Example 1 is larger than the instantaneous velocity found in Example 2. (Hint: Sketch the graph of velocity as a function of time. Is the function increasing or decreasing? What does that tell you about how...
