15. The period of the vertical oscillations of a mass hanging from a spring is known to be constant.
(a) A student times single oscillations with a stopwatch. In 10 separate measurements, the
stopwatch readings were:
1.8 s, 1.9 s, 1.7 s. 1.9 s, 1.8 s, 1.8 s, 1.9 s. 1.7 s, 1.8 s, 1.8 s.
What is the best value obtainable from these readings for the time of one oscillation?
Explain how you arrive at your answer.
best value =
explanation
(b) Describe how, using the same stopwatch, the student can find the period of oscillation
more accurately

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
