A mass attached to a spring oscillates with a period of 3.35 s.

(a) If the mass starts from rest at x = 0.0340 m and time t = 0, where is it at time t = 5.96 s?
(b) Why is the mass moving in a positive direction at t = 5.96 s?

Question

A mass attached to a spring oscillates with a period of 3.35 s.

(a) If the mass starts from rest at x = 0.0340 m and time t = 0, where is it at time t = 5.96 s?
(b) Why is the mass moving in a positive direction at t = 5.96 s?

mani_jha · Answer

The equation of simple harmonic motion is:
$$x=A \sin (wt+\alpha)$$
$$w=2\pi/T$$
T is time period.
A=0.034m
Now can you substitute the given values in the equation, and find what is being asked for?
