Mavis boards a spaceship and then zips past Stanley on earth at a relativespeed of 0.600c. At the instant she passes him, they both starttimers. (a) A short time later Stanley measures that Mavis has traveled9.00 * 10^7 m beyond him and is passing a space station. What doesStanley’s timer read as she passes the space station? What does Mavis’stimer read? (b) Stanley starts to blink just as Mavis flies past him, andMavis measures that the blink takes 0.400 s from beginning to end.According to Stanley, what is the duration of his blink?

Two students, Nora and Allison, are both the same age when Allison hops aboard a flying saucer and blasts off to achieve a cruising speed of 0.790c for a 17.5 year round trip (according to Allison). Neglecting the brief time periods required for the acceleration of the ship during blastoff and turnarounds, find the difference in age between Nora and Allison when they are reunited, difference in age: years Who is older? Allison They are still the same age. need more information Nora

An electron moving at 0.80c relative to the Earth reference frame travels the 100m length of a building (as measured in the Earth reference frame). What is the length of the building according to an observer moving along with the electron?

A particle Q move from left to right at a speed of 0.85c.  A second particle R moves from left to right at a speed of 0.8c, and a third particle S moves from right to left at speed -0.8c.     Find:   A)The speed of particle R relative to particle Q.   B)The speed of particle S relative to particle Q.

Spaceships A and B move in opposite directions at the same speed of  0.907c  relative to earth, with A moving away from earth and B moving toward earth. Find the velocity of B relative to A.

Two rockets moving towards each other. Rocket A moving to the right with speed 0.80c while rocket B moving to the left with speed 0.60c. The length of the two rockets are the same, that are 50m as measured by the earth observer.  i) What is the lengths of the two rockets as measured by the astronouts in their rockets? ii) What is the velocity of the rocket relative to each other? iii) If the earth observer measured the initial distance of the two rockets to be 2.52 x 1012 m apart, what are distance of the two rockets observed by observer in the rockets? iv) How long before they collide, observed by the observer in the rockets?  v) If both rockets could evacuate within 90 min (their own time), will they survive?

If possible please do this on a computer. Thank you A spaceship passes you at a speed of 0.90c. You find the length of the ship in your frame of reference to be 50.0 m. A few months later, the ship docks, and you measure its length with a tape measure. What length does the tape measure show?
