Point P is on the rim of a wheel of radius 2.0 m. At time t = 0, the wheel is at rest, and P is on the x axis. The wheel undergoes a uniform angular acceleration of 0.01 rad/s^2 about the center O.
In Figure 9.1, the magnitude of the linear acceleration of P, when it reaches the yaxis, is closest to:

.020m/s^2
