A complete description of simple harmonic motion must take into account several physical quantities and various mathematical relations among them. This information is needed to solve oscillation problems of this type.
The position of a 45 g oscillating mass is given by x(t)=(2.0cm)cos(10t), where t is in seconds.
a. Determine the velocity at t=0.40s.
b. Assume that the oscillating mass described in Part A is attached to a spring. What would the spring constant k of this spring be?
c. What is the total energy E of the mass described in the previous parts?
