Question

A mass is attached to the end of a spring. The spring is extended and the mass on the end of the spring begins to bob up and down in simple harmonic motion where its displacement at any time, t, from ), the equilibrium position, is given by the equation
x(t) = -10 cos (pi)t

a)Find the times at which the particle is stationary.

b)Find when the velocity is a maximum and when it is a minimum

c) Find the points where the acceleration is 0. What do you notice about the velocity at these points?
