# Note that the total acceleration

Grover
Here's a problem from my textbook. Hope somebody could give a hand.
The speed of a particle moving in a circle 2m in radius increases at the constant rate of 3m/s^2. At some instant, the magnitude of the total acceleration is 5m/s^2. At this instant, find the centripetal acceleration of the particle and its speed.
