A spaceship of 50 meters in length is launched from the Earth.
Somehow, it reaches a
speed of 0.8 times the speed of light. If we view it from its
longest direction, what angle
will it subtend when it is at the distance of Neptune?

A spaceship at rest on the earth has a length of 120m and a mass of 16,000kg. Then the spaceship begins to move away from the earth at 3/4 speed of light. If the spaceship sends out a second ship away from the earth on what observers on the spaceship think is 1/2 speed of light, how fast do the observers on earth think the second ship is moving? If the spaceship sends out a second ship toward the earth...

15 pts) A spaceship flying directly toward Earth at 0.7c launches a missle with a speed (measured m the spaceship) of 0.8c at an angle of 60 (measured from the spaceship and measured relative to the ship-Earth direction). What is the speed of the missle measured by people on Earth and what is the angle of the missle's trajectory relative to the ship-Earth direction as measured by people on Earth?

Practice Problem 27.3 SOLUTION A spaceship flies past earth with a speed of 0.980c (about 2.97 x 10 m/s) relative to earth. A crew member on the spaceship measures its length, obtaining the value 400 m. What is the length measured by observers on earth? SET UP The length of the spaceship in the frame in which it is at rest (400 m) is a proper length in this frame, corresponding to lo in We want to find the length...

suppose a spaceship heading directly away from the Earth at 0.75c can shoot a canister at 0.65c relative to the ship. Take the direction of motion towards Earth as positive. v1= 0.75 c v2= 0.65 c a) If the canister is shot directly at Earth, what is the ratio of its velocity, as measured on Earth, to the speed of light? (units for answer in mu/c=...) b) What about if it is shot directly away from the Earth (again, relative...

A ladder leans against a wall inside a spaceship. From the point of view of a person on the ship, the base of the ladder is 2.50 m from the wall, and the top of the ladder is 5.01 m above the floor. The spaceship moves past the Earth with a speed of 0.89c in a direction parallel to the floor of the ship. What is the length of the ladder as seen by an observer on Earth?
