- A super rocket car traverses a straight track 2.30×105 m long in 1.00×10−3 s as measured by an observer next to the track. How much time delta t(clock) elapses on a clock in the rocket car during the run? delta t(clock) = ?s What is the distance L(driver) traveled in traversing the track as determined by the driver of the rocket car? L(driver) = ?mA spacecraft flies past the earth in the direction toward the moon, a distance of 3.84 * 10^5 km. As measured by your clock on the earth, it takes 6.00 s for the clock on the spacecraft to tick off 2.00 s. You measure the length of the spacecraft in the direction of its motion to be 24.0 m. As measured by an astronaut at rest on the spacecraft, what are (a) the distance from the earth to the moon and (b) the length of the spacecraft?A UFO is observed directly above the earth moving at a constant velocity. An astronaut on the moon (3.8 x 108m from earth) observes the UFO passing overhead 5.8 s later. From the UFO's reference frame, how long did it take to travel from the earth to the moon?

- Two electrons are brought close together, to a distance of 75 pm apart. They are then both released from rest, accelerating and travelling away from one another. When the two particles are very far apart, how fast will they be going, in m/s?Someone in Earth's rest frame says that a spaceship's trip between two planets took 10.0 years, while an astronaut on the space ship says that the trip took 6.27 years. Find the speed of the spaceship (as measured by someone in Earth's rest frame) in terms of the speed of light. 0.959c 0.687c 0.489c 0.684c 0.779cA spaceship moves by Earth at 2.8×108 m/s. A satellite moves by Earth in the opposite direction at 1.3×108 m/s. Use the Galilean transformation to calculate the speed vsatellite,x of the satellite relative to the spaceship. vsatellite,x = ? m/s
- A rocket cruising past earth at 0.500 ⋅c⋅c shoots a bullet out the back door, opposite the rocket's motion, at 0.750 ⋅c⋅c relative to the rocket. What is the bullet's speed relative to the earth? What is the direction of its movement? along the rocket's motion opposite the rocket's motionA cosmic ray particle is released from an exploding star that is 2600 Light Years from Earth. If the particle traveled at 98% the speed of light, how far did it travel in its own frame of reference before hitting Earth?A clock is moving at v =(4/5)c. c is the speed of light. The clock passes our clock when both clocks read t = 0. When the moving clock reads t = 30 s, what will the clocks in our frame read?
