A rocket leaves a space station in the positive-x direction and a laser-produced beam of light is sent out from the space station in the positive-y direction i.e. the rocket and the light beam leave the space station along perpendicular paths. Measured relative to the space station, the rocket moves at 0.6c. What is the velocity and speed of the light beam as observed by an observer in the rocket? *Please do not just answer with the speed of light,...

The figure below shows a block with mass m = 5.3 kg pulled up a ramp inclined at an angle of 6 = 28° with a force of magnitude F = 33 N parallel to the ramp. m (a) If there is no friction between the block and the ramp, what is the magnitude of the block's acceleration (in m/s2)? 1.485 Draw a free-body diagram. What forces act on the block? Let the x-axis be parallel to the incline. What...

An astronaut out on a spacewalk to construct a new section of the International Space Station walks with a constant velocity of 1.50 m/s on a flat sheet of metal placed on a flat, frictionless, horizontal honeycomb surface linking the two parts of the station. The mass of the astronaut is 78.0 kg, and the mass of the sheet of metal is 250 kg. (Assume that the given velocity is relative to the flat sheet.) (a) What is the velocity...

4) An astronaut standing at radius R1 on the inner ring of this space station moves a distance X1 along a circular arc as the station rotates. A) Over what distance X2 does another astronaut at radius R2 on the outer ring move in the same time? B) Over what angle, in degrees, did the space station rotate in this period, expressed in terms of R1 and X?

A space station is constructed in the shape of a hollow ring of mass 4.85 x 104 kg. Members of the crew walk on a deck formed by the inner surface of the outer cylindrical wall of the ring, with radius 140 m. At rest when constructed, the ring is set rotating about its axis so that the people inside experience an effective free-fall acceleration equal to g. (See figure below.) The rotation is achieved by firing two small rockets...

A racetrack has the shape of an inverted cone, as the drawing shows. On this surface the cars race in circles that are parallel to the ground, and the surface is at an angle θ = 40°. For a speed of 23 m/s, at what value of the distance d should a driver locate his car if he wishes to stay on a circular path without depending on friction?

You are the astrogator on a starship that has just left a space station one hour ago heading toward galactic East at half light speed. The captain receives orders listing the coordinates of a rendezvous with another ship as (1 light-hour North, 2 light-hours East). The coordinates, of course, are measured relative to the space station, and the captain wants them translated into coordinates relative to your starship. What do you tell him?

After a space station is constructed, it is spun up from rest,
using rockets attached tangentially to the outside hull, in order
to simulate earth gravity for the occupants inside, shown in the
figure. We can model the station as a hoop that rotates around its
axis, and ignore the rest of the structure for the moment of
inertia.
The mass of the station is m = 50,000 kg, the outer
radius is r = 100 m.
a) The two...

what is the period of rotation
gure shows a space station. It has the shape of a hollow ring, with diameter D = 480 m. Review Part A The space station rotates in order to simulate Earth's gravity - so that the normal force on an astronaut at the outer edge would be the astronaut's weight on Earth. What is the period of the rotation Time for one complete revolution needed to achieve this? Express your answer to 2 significant...
