## Homework Statement

## Homework Equations

x = A cos(wt-phi)

## The Attempt at a Solution

Using the above equation for t, calculating values for t

_{1}at -0.05 and t

_{2}at 0.05, as well as assuming phase angle phi is zero, I get an answer of over 40 seconds.

I think I may be using the wrong equation or perhaps assuming the value of phi incorrectly. Help is appreciated.
