**1. Homework Statement**

A rocket is accelerating upward at 4.00 m/s^2 from the launchpad on the earth. Inside a small 1.50-kg ball hangs from the ceiling by a light 1.10-m wire. If the ball is displaced 8.50 degrees from the vertical and released, find the amplitude and period of the resulting swings of the pendulum.

**2. Homework Equations**

T = 2pi \sqrt{L/g}

\omega = /sqrt{g/L}

x = Acos(\omegat + \phi)

**3. The Attempt at a Solution**

I think this is a simple pendulum problem.

T = 2pi /sqrt{1.1/4} = 3.29 s, I relplaced g with the upward acceleration of the rocket.

I'm trying to solve for A from the equation that I have for x, but I don't have t.
