## Homework Statement

A 1.10 kg mass on a spring has displacement as a function of time given by the equation

x(t)=(7.40cm)cos[(4.16rad/s)t−2.42rad].

Find the position of the mass at t=1.00s;

## Homework Equations

x = Acos(ωt+∅)

## The Attempt at a Solution

I tried to just plug in the time t in that equation to solve for the displacement, but I'm getting 0.074 which apparently is not the right answer:

x = 0.0740m*cos(4.16rad/s(1.00s) - 2.42rad)

x = 0.074
