Question

The tip of a wall clock’s minute hand measures 2.0 m from the floor at 10:00. At 10:30 it measures 1.7 m from the floor. If the motion of the minute hand is modeled as a cosine graph over a time of several hours, what would be the period and amplitude of the graph?

Period = 45 min Amplitude = 2.0 m
Period = 60 min Amplitude = 0.15 m
Period = 15 min Amplitude = 0.15 m
Period = 30 min Amplitude = 0.30 m

Accepted Answer

Period = 60 min  Amplitude = 0.15 m

Answer

Period = 30 min  Amplitude = 0.30 m

Answer

Period = 15 min  Amplitude = 0.15 m

Answer

Period = 45 min  Amplitude = 2.0 m
