100%
A counterweight of mass \( m = 4.10 \, \text{kg} \) is attached to a light cord that is wound around a pulley as shown in the figure below. The pulley is a thin hoop of radius \( R = 7.00 \, \text{cm} \) and mass \( M = 1.80 \, \text{kg} \). The spokes have negligible mass.

**Figure Description:**
The image depicts a pulley system. A pulley is shown with a hoop and a counterweight \( m \) hanging downwards from a cord wrapped around the pulley. The radius of the pulley is labeled \( R \), and the mass of the pulley hoop is labeled \( M \).

**Problems:**

(a) What is the net torque on the system about the axle of the pulley?
- Enter the magnitude: \(\underline{\hspace{2cm}}\) N·m
- Direction: [Select]

(b) When the counterweight has a speed \( v \), the pulley has an angular speed \( \omega = v/R \). Determine the magnitude of the total angular momentum of the system about the axle of the pulley.
- \((\underline{\hspace{2cm}} \, \text{kg} \cdot \text{m})v\)

(c) Using your result from (b) and \(\vec{\tau} = \frac{d\vec{L}}{dt}\), calculate the acceleration of the counterweight. (Enter the magnitude of the acceleration.)
- \(\underline{\hspace{2cm}}\) m/s²
