**1. Homework Statement**

I have an angular acceleration question. I have two different scenarios I want to compare. The difference is the distance from rotational center point.

The

**input torque is 1Nm**in both scenarios. I want to a

**ccelerate a mass of 2kg**over an

**90 degree angle (0.5PI rad)**.

My question is, what is the

**peripheral velocity and the kinetic energy of the 2 kg mass, at the end of the 0.5PI rad rotation?**

**Scenario 1.**The 2kg mass, have it's center of gravity

**1.0m**from the rotational center point.

**Scenario 2.**The 2kg mass, have it's center of gravity

**1.2m**from the rotational center point.
