An object is oscillating with a frequency of 2.5 Hz and has a maximum displacement of 4.0 cm at t = 0 seconds. The magnitude of the displacement of the object at t = 0.75 seconds is
A) zero.
B) 1.7 cm.
C) 2.8 cm.
D) 3.9 cm.

Question

Quizplus · Accepted Answer

The displacement in simple harmonic motion can be calculated using the formula x(t) = A * cos(2πft), where A is the amplitude and f is the frequency. Substituting the given values, x(0.75) = 4.0 * cos(2π * 2.5 * 0.75) = 2.8 cm.
