A 2.0 kg mass is connected to a spring with a spring constant of 9.0 N/m. The displacement is given by the expression x(t) = (12 cm) sin(ω t). What is the amplitude of the motion?
A) 8.0 cm
B) 12 cm
C) 20 cm
D) 24 cm
E) 30 cm

Question

Quizplus · Accepted Answer

The amplitude of the motion is given by the maximum displacement from the equilibrium position. Since the displacement is given by x(t) = (12 cm) sin(ω t), the maximum displacement is 12 cm. Therefore, the amplitude of the motion is 12 cm. So, the best choice is B.
