- 4. A ladder leans against a wall inside a spaceship. From the point of view of person on the ship, the base of the ladder is 2.00 m from the wall, and the top of the ladder is 5.66 m above the floor. The spaceship moves past the Earth with a speed of 0.95c in a direction parallel to the floor of the ship. Find the angle the ladder makes with the floor, as seen by an observer on Earth. f60 ssf60 ssf60 s sf60 ssforce 50 ssf60 s ssf60 ssfoCompute the kinetic energy of a proton (mass 1.67 x 10-27 kg) using both the nonrelativis- tic and relativistic expressions (a) 8.0 x 107 m/s and (b) 2.858 m/sA spaceship travels from the Earth to a star 13 light years away (as measured in the Earth’s frame). An astronaut on the ship says that the trip takes 16 years. What is the speed of the ship relative to the earth in m/s?
- What is the discrepancy (according to an observer on the surface of the Earth), due to the general relativistic (i.e. gravity-based) time dilation, between the clock on a particular communications satellite and a clock on the surface of the Earth after 1 day. Ignore the sign of the discrepancy. Orbital Radius of satellite = 4.0 x 10 m 6.37 x 106 m %3D Radius of the Earth = Mass of Earth = 5.97 x 1024 kg Gravitational Constant = 6.67 x 10-11m3 kg-1 s-2 Speed of light =3 x 108 m/s %3DA rocket speeds by the earth at 0.77c. The earthlings measure the moving rocket to be 158 m long. What is the length of the rocket as measured by the passengers on the rocket? Please give your answer in meters. 247.63The distance to a particular star, as measured in the earth's frame of reference, is 7.11 light- years (1 light-year is the distance that light travels in 1 y). A spaceship leaves the earth and takes 3.35 y to arrive at the star, as measured by passengers on the ship. (a) How long does the trip take, according to observers on earth? (b) What distance for the trip do passengers on the spacecraft measure?
- Consider a 5.75 m long sports car going past you at great speed. How fast would it have to be going past you in order for it to appear only 5.25 m long? Give you answer as a ratio of the velocity to the speed of light c. v/c=A star is 12.2 ly (light-years) from Earth. HINT (a) At what constant speed (in m/s) must a spacecraft travel on its journey to the star so that the Earth–star distance measured by an astronaut onboard the spacecraft is 4.36 ly? m/s (b) What is the journey's travel time in years as measured by a person on Earth?
