Homework Statement
A spinning disk has an angular velocity (Va) of 2 rad/s and an angular acceleration (Aa) of 3 rad/s2. A point on the disk (x) is 1 m from the center of the disk. What is the magnitude of this point x's acceleration in m/s2?
Is it the sum of the the tangential acceleration plus the centripetal acceleration?
The Attempt at a Solution
Using the angular acceleration and point x's radius I found it's acceleration to be 3 m/s^2
Then, using Ac = V2 / r, I found the centripetal acceleration to be 4 m/s2.
Now that I have these values do I add their scalar values or their vector values?
