- At what relative velocity is Ƴ = 2.00 ?Consider a 5.75 m long sports car going past you at great speed. How fast would it have to be going past you in order for it to appear only 5.25 m long? Give you answer as a ratio of the velocity to the speed of light c. v/c=Car A is moving east at 63 kph while Car B is moving in the direction of N 45° E. For a passenger in Car A, B appears to be moving away in a direction of N 30° W. Solve for the velocity, in kph, that B appears to the passengers in A. Round your answer to 2 decimal places.
