A meter stick(1m), placed perpendicular to the x-axis, is travelling at 0.6c in the direction of the positive x-axis. To a stationary observer, how long does the meter stick appear to be?

The distance from earth to the center of our galaxy is about 33,000 ly (1 ly = 1 light year = 9.47 x 1015 m), as measured by an earth- based observer. A spaceship is to make this journey at a speed of 0.9990c. According to a clock on board the spaceship, how long will it take to make the trip? Express your answer in years. (1 yr is equal to 3.16 x 107 s.) Number i d Modic Units

A spaceship travels at 0.758c relative to Earth. If the spaceship fires a small rocket in the forward direction, how fast (relative to the ship) must it be fired for it to travel at 0.878c relative to Earth?

Fred travels past Alice at a constant speed of 0.921c in the positive x direction. Fred is holding a meter stick at an angle of 26.3° with respect to the +x axis. What is the length (in m) and orientation (in degrees) of the meter stick according to Alice?

A car traveling at 35.0 m/s takes 26.0 minutes to travel a certain distance according to the driver’s clock in the car. How long does the trip take according to an observer at rest on Earth? Hint: The following approximation is helpful:

An astronaut floating in the International Space Station moves at 0.40 m/s to the right. After 5.0sec have passed they are now moving at 1.30 m/s to the left. What was their acceleration duringthis time, stating both the magnitude and direction?

The distance from earth to the center of our galaxy is about 24,000 ly (1 ly = 1 light year = 9.47 x 1015 m), as measured by an earth- based observer. A spaceship is to make this journey at a speed of 0.9990c. According to a clock on board the spaceship, how long will it take to make the trip? Express your answer in years.

An astronaut travels to the next star at a speed of 0.95c and back. He notices that his trek has taken him 11 years. When he returns, how much time will have elapsed on Earth during his absence?

A spaceship carrying a light clock moves at a speed of 0.6c relative to an observer on Earth. If the clock on the ship advances by 1.00 s as measured by the space travelers aboard the ship, how long did that advance take as measured by the observer on Earth? O 1.15 s O 1.25 s O 3.6 s O 2.6 s O 0.96 s
