Determining acceleration and velocity of an astronaut.

A cylindrical space station located in distant space, rotates with constant angular velocity about its axis. Astronaut Olivia rotates with the station and she is located at the perimeter, a distance R from the axis of rotation.


True or False? Olivia's acceleration is not zero.
True or False? Olivia's velocity is not constant.

False and true. Acceleration needs a point of comparison for the change in velocity. As she rotates with the space station her point of comparison remains the same. In regards to her velocity, it is always changing due to the cylindrical nature of her movement. Velocity is speed in a given direction. If her speed remains the same but her direction is always changing her velocity by definition is changing also.

Hmm you don't look like the physics type...
