- Tom is moving at 19.1 m/s i-hat relative to Ann. Bob is moving at 17.1 m/s i-hat relative to Ann. Bob is moving at 27.6 m/s i-hat relative to Sue. What is the velocity of Bob relative to Tom?The principle of relativity was recognised as both a mechanical and optical effect. Einstein believed that the principle should hold for both situations. One of his thought experimentds involves him sitting on a train travelling at the speed of light and looking at a mirror. He asked the question as to whether he would be able to see his own reflection. a) Outline one possible answer to Einstein's question and the problems involved in your answer in terms of the principle of relativity. b) What was Einstein's conclusion to this thought experiment?c) The theory of relativity discusses the physical consequences of a universal frame of reference. The special theory of relativity, published in 1905 by Albert Einstein, is concerned with problems involving inertial frame of reference. Its fundamental principles, however, caused discrepancies in measurements. Describe TWO apparent discrepancies caused by these fundamental principles.Answers are not 96.537 or 96.415. I can not seem to figure out what I am doing wrong for part a. Thank you for the help in advance.

Given: Three forces act on particle P. Force A has a magnitude of 15 N and acts 60° CCW from the positive x-axis. Force B has a magnitude of 60 N and acts along a ray from point P with a slope of -4/3. Force C has a magnitude of 10 N and acts straight left (180° CCW from positive x- axis). Find the Vector Sum: a. Draw a neat, labeled, scaled diagram representing the tip-to-tail vector addition R=A+B+C. Rx = 15cos60+60(3/5) — 10 and Ry = 15sin60-60(4/5) b. Add the three vectors to find the scalar components of the resultant, Rx and Ry. C. Find the magnitude of the resultant R and the angle 0 it makes with the positive x-axis.What is the FWHM of this curve?
