Uniform Circular Motion Prelab Assignment
4-digit Code Number:_______________________________
- A mass m is attached to a spring and whirled in a circle at
constant speed in intergalactic space, far from any gravitating
bodies. Draw a free-body diagram for the mass, labeling and
describing all forces indicated.
- If the mass is 15 cm from the axis of rotation and makes 25 revolutions
in 10 seconds, what is its speed in m/s?
- If m = 0.1 kg and the values in part (b) still hold, what are the
numerical values of all forces in part (a)?
- If the 0.1 kg mass is suspended at rest from the same spring near the
Earth's surface, the distance that the spring is stretched is measured
to be 1.0 cm. What is the spring constant of the spring (remember the
