The radius of Earth is 6370 km, and its orbital speed about the Sun is 30 km/s. Suppose Earth moves past an observer at this speed. To the observer, by how much does Earth’s diameter contract along the direction of motion?
You encounter a moving walkway that is 75 mm long and has a speed of 1.9 m/sm/s relative to the ground.How long would it take you to cover the 75 mm length of the walkway if, once you get on the walkway, you turn around and start walking in the opposite direction with a speed of 1.4m/s relative to the walkway?
1. Consider a bouncy ball and a metal cylinder on a 20 degree incline. Everyone knows a regular bouncy ball has a diameter of 2.5 cm and has a mass of 29 g, the cylinder is 5 cm long with a diameter 1 cm. 1. Use the conservation of energy approach to find the length of time theobjects in #1 take to roll down a 1.5 m incline at 200.t =_________________________ and ____________________________ If you could clearly circle the answers I need, that would be great!!

I know that the answer for this question is "c" but could you explain me how or why?
Quite apart from effects due to Earth’s rotational and orbital motions, a laboratory reference frame is not strictly an inertial frame because a particle at rest there will not, in general, remain at rest; it will fall. Often, however, events happen so quickly that we can ignore the gravitational acceleration and treat the frame as inertial. Consider, for example, an electron of speed v =0.992c, projected horizontally into a laboratory test chamber and moving through a distance of 20 cm. (a) How long would that take, and (b) how far would the electron fall during this interval? (c) What can you conclude about the suitability of the laboratory as an inertial frame in this case?
How do i find the minimum speed?
Electrons in a 2 mi linear accelerator reach a final velocity vf = 0.9999999997c. How long would it take an electron to reach the end of the accelerator as seen by the accelerator?

It has a carpeted floor, curtains on both sides, plasterboard (or equivalent) short sides, and a plasterboard ceiling. what will the reverberation tiume be if it is occupied by twenty people in comfortable upholstered seats?
A space vehicle is coasting at a constant velocity of 17.1m/s in the +y direction relative to a space station. The pilot of the vehicle fires a RCS (reaction control system) thruster, which causes it to accelerate at 0.324m/s^2 in the +x direction. After 35.1s, the pilot shuts off the RCS thruster. After the RCS thruster is turned off, find the magnitude and the direction of the vehicle's velocity relative to the space station. Express the direction as an angle (in degrees) measured from the +y direction.
