Question

A glider attached to one end of a string oscillates given by the displacement function . What is the displacement of the mass after 1.52 seconds?

Answer 1

Unfortunately, from the condition of the question we don't know the displacement function. Let's suppose that the displacement function given as follows:

$$x(t)=0.030cos(4.0t)$$

Then, the displacement of the mass after 1.52 seconds will be:

$$x(t=1.52\ s)=0.030\ m\times cos(4.0\times1.52\ s)=0.029\ m.$$
