• Classical mechanics is a well-tested model established by hundreds of years of experiments and achievements in engineering that have confirmed its validity. If special relativity significantly deviated from classical physics in everyday situations, it would be directly contradicted by a vast amount of evidence. In this problem, you will learn how some laws of classical mechanics can be derived from special relativity when we assume that the speeds involved are much smaller than the speed of light. Two surprising outcomes of special relativity are time dilation and length contraction, which suggest that time and space measurements change depending on the observer. The equations for time dilation and length contraction are t = γt0 and l = l0/γ, respectively, where γ = 1/sqrt(1-u^2/c^2). Part A Determine the first two terms of the binomial expansion for γ. Express your answer in terms of u and c. Hints: γ ≈ 1 + 1/2(u/c)^2 Submit My Answers Give Up Correct You can see that γ approaches 1 if u << c, which is true for most cases. Using γ = 1 in the equations for time dilation and length contraction retrieves the classical physics equations, indicating no time dilation or length contraction. This is why length contraction and time dilation are not noticeable in daily life. Part B Consider a case with a speed uncommon in everyday life: a spy plane moving at 1500 m/s. Calculate the deviation from classical predictions (γ ≠ 1) that relativity anticipates at this speed using only the first two terms of the binomial expansion. Express your answer to four significant figures. γ - 1 ≈ 1.250×10^-11 Submit My Answers Give Up Correct If you lived for 70 years on such a spy plane moving at 1500 m/s, you would experience a total time difference of about 28 ms compared with someone at rest relative to Earth when you landed. Hence, relativistic effects are not noticeable in daily life or at its edges. However, using atomic clocks, which can measure time with precision up to one part in 10^13, time dilation at typical airliner speeds has been confirmed. Part C Now consider the relativistic velocity addition formula: speed = (v + u)/(1 + vu/c^2). If v = u = 0.01c (1% of c), what is the relativistic sum of the two speeds? Express your answer as a percentage of the speed of light to five significant figures.
