A common approach to create artificial gravity in outer space is to rotate a hollow cylindrical object at some rotational velocity.
a. Given a space wheel with a 250 m diameter and a rotational period of 18 seconds, what is the apparent gravity felt for someone walking on the interior walls?
b. What exactly is causing theartificial gravity? This process is shown to be effective in movies, but cannot be applied in real life. Why not?
A fish swimming in a horizontal plane hasvelocity vi =(4.00 i + 4.00 j) m/s at a point in the oceanwhere the position relative to a certain rock isri =(10.0 i + 4.00 j) m. After the fish swimswith constant acceleration for 21.0 s, itsvelocity is v..
