Title: Calculating Net Work for a Merry-Go-Round

**Scenario:**

A merry-go-round has a mass of 1470 kg and a radius of 6.80 m.

**Problem (Part A):**

Determine the amount of net work required to accelerate the merry-go-round from rest to a rotation rate of 1.00 revolution per 7.70 seconds. For the purpose of this calculation, assume the merry-go-round is a solid cylinder.

**Instructions:**

- Express your answer using three significant figures.
- Include the appropriate units in your final answer.

**Calculation Area:**

\[ W = \text{Value} \quad \text{Units} \]

**Note:**

In this problem, you will apply the concepts of rotational motion and work-energy principles for a rigid body to determine the work done on the system. Be sure to consider the moment of inertia for a solid cylinder in your calculations.

**Part A**

What is the angular momentum of a 3.0-kg uniform cylindrical grinding wheel of radius 29 cm when rotating at 1500 rpm?

*Express your answer using three significant figures and include the appropriate units.*
