Question

And object is undergoing simple harmonic motion along the x-axis. Its position is described as a function of time by x(t) = 2.7 cos(3.1t – 1.2), where x is in meters, the time, t, is in seconds, and the argument of the cosine is in radians.

A) Find the amplitude of the simple harmonic motion, in meters.

B) What is the value of the angular frequency, in radians per second?

C) Determine the position of the object, in meters, at the time t = 0.

D) What is the object’s velocity, in meters per second, at time t = 0?

E) Calculate the object’s acceleration, in meters per second squared, at time t = 0.

F) What is the magnitude of the object’s maximum acceleration, in meters per second squared?

Please show all work

Answer 1

This is corrected answer in, my previous answer i put did values in degrees instead of radians.
