An object is undergoing shm with period 0.900 s and amplitude 0.320 m. at t = 0 the object is at x = 0.320 m and is instantaneously at rest. calculate the time it takes the object to go (a) from x = 0.320 m to x = 0.160 m and (b) from x = 0.

Your friend states in a report that the average time required to circle a 1.0-mi track was 49.325 s. This was measured by timing 10 laps using a stopwatch with a precision of 0.01 s. Do you believe his results are reliable? Explain.
