An observer on the ground and another one on a train are observing a plane flying above. The speed of the plane is 5 times the speed of the train. A third observer is sitting on a seat inside the plane. The ground observer notices that two lightning bolts hit the two ends of the plane at the exact same time (simultaneously) for him. Event 1 is the lightening hitting the back of the plane and Event 2 is the lightening hitting the front of the plane. Which statement below is true of the other two observers? (Assume all 3 observers have extremely accurate clocks)

- A 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?Electromagnetic radiation from a star is observed with an earth-based telescope. The star is moving away from the earth with a speed of 0.580c. If the radiation has a frequency of 8.64 x 1014 Hz in the rest frame of the star, what is the frequency measured by an observer on earth?Your answer is partially correct. As the drawing shows, a carpenter on a space station has constructed a 30.0° ramp. A rocket moves past the space station with a relative speed of 0.773c in a direction parallel to side x. What does a person aboard the rocket measure for the angle of the ramp? Number MO 42.50 Units 30.0° X A

At t = 0 seconds, A and B are 1 km apart, their speeds are VA = 110 kph and Ve = 60 kph and they are at points P and Q respectively. Knowing that A passes point Q. 40 seconds after B was there and that B passes point P, 42 seconds after A was there. Question 6 Question 7 Question 8 Determine the time when they pass each other.

One is a woman and one is a man. The woman moves away with a velocity of +2.0 m/s relative to the ice. The mass of the woman is 57 kg, and the mass of the man is 76 kg. Assuming that the speed of light is 3.5 m/s, so that the relativistic momentum must be used, find the recoil velocity of the man relative to the ice.

Charged pions are unstable particles that decay into muons with a half-life of 1.8 x 10-8 s. Pions have been investigated for use in cancer treatment because they pass through tissue doing minimal damage until they decay, releasing significant energy at that point. The speed of the pions can be adjusted so that the most likely place for the decay is in a tumor.Suppose pions are created in an accelerator, then directed into a medical bay 30 m away. The pions travel at the very high speed of 0.99995c. Without time dilation, half of the pions would have decayed after traveling only 5.4 m, not far enough to make it to the medical bay. Time dilation allows them to survive long enough to reach the medical bay, enter tissue, slow down, and then decay where they are needed, in a tumor. The proton collision that creates the pion also…
- Antimatter: When a particle and its anti-particle collide, energy and momentum are conserved. However, the particles can annihilate each other and produce two gamma rays - high energy photons. An electron and an anti-electron each have a rest mass of 9.11 × 10-31 kg. Suppose the particles are each accelerated to a speed of 0.98c in a particle accelerator with a length of 1543 m for a head on collision. (Each particle is moving at this speed with respect to the lab, and the particles are moving in opposite directions.) They collide head on and annihilate. What is the wavelength of the gamma rays produced in this collision?Starship "A" is traveling at 0.8c with respect to the identical starship "B". Each starship has rest length 10000 m.

What result should he get? 12500 m 15000 m 8000 m None of the answers 6000 mA ship launches a rocket with a velocity of 0.70c to the right of the spaceship.
