3. a) As shown in Figure 3a, a hibernating astronaut in a ship at rest lies on a recliner making an angle = 35° with the horizontal. The height of the recliner is y = 1.15 meters. In Figure 3b, the ship is moving at velocity v = 0.75c with respect to a stationary observer. Calculate the value of the Lorentz factor y. What is the observed angle e' of the length-contracted recliner? Figure 3b. Relativity: 1 - 22 ť=yto...

PLEASE ANSWER BOTH!!!
Our best measurements from Earth indicate that the star system Alpha Centauri is 4.2 light-years away. Suppose some of our astronauts traveled there at a speed v 0.83c. What would the astronauts measure as the distance to Alpha Centauri? O 2.8 light-years 9.1 light-years O 2.9 light-years O 2.3 light-years O 7.5 light-years If a proton with mass 1.67 x 10"27 kg moves in an accelerator such that its total energy is five times its rest energy...

What are the Solutions to Part B of Chapter 2 of Tillery Physics 9th edition.......kinda pointless for you guys to only have the solutions that the book has already. 1. What was the average speed in km/h of a car that travels 400.0 km in 4.5 h? 2. What was the average speed in km/h of a boat that moves 15.0 km across a lake in 45 min? 3. How much would a 80.0 kg person weigh (a) on Mars,...

Please work out 3 clearly and with units. Thanks!
1. A 10-g bullet travels vertically upwards at 1000 m/s, then strikes and passes through a 2.0-kg block initially at rest. The bullet emerges from the block with a speed of 400 m/s because it transfers momentum to the block. (a) How much momentum did the block gain? (b) How fast is the block now moving, and what is its kinetic energy? (c) Using energy considerations only, to what maximum height...

A right triangle has hypotenuse 13 cm and one side 7 cm. Find the length of the other side, and the sine, cosine and tangent of each of the other two angles. A man running 4 m/s is passed by a car at 20 m/s, both heading East. What is the velocity of the man relative to the car? How far apart are the 20 seconds after the car passes the man? A ball is thrown vertically upwards from the...
