Assume that the speed of light in a vacuum has the hypothetical value of 18.0 m/s. A car is moving at a constant speed of 14.0 m/s along a straight road. A home owner sitting on his porch sees the car pass between two telephone poles in 4.95 s. How much time does the driver of the car measure for his trip between the poles?|||T = t/sqrt(1 - (v/c)^2) = 4.95 sec is the observer's time interval; solve for t = ? the driver's comparable interval when v/c = 7/9. t = T sqrt(1 - (v/c)^2) = 4.95 sqrt(1 - 49/81) = 3.11 seconds give or take a tick.
