Question
**Physics Experiment: Circular Motion of an Air Puck**

An air puck of mass \( m_1 = 0.17 \, \text{kg} \) is tied to a string and allowed to revolve in a circle of radius \( R = 1.2 \, \text{m} \) on a frictionless horizontal table. The other end of the string passes through a hole in the center of the table, and a mass of \( m_2 = 1.3 \, \text{kg} \) is tied to it. The suspended mass remains in equilibrium while the puck on the tabletop revolves.

**Diagram Explanation:**
- The diagram features a horizontal table with a puck tied to a string. 
- The string passes through a hole at the table's center and supports a mass hanging below.
- The puck revolves in a circular path with radius \( R \), indicated by a dashed circle on the table's surface.
- The vectors show the direction of the puck’s velocity and the tension in the string.

**Questions:**
(a) What is the tension in the string (in N)?

(b) What is the horizontal force acting on the puck (in N)?

(c) What is the speed of the puck (in m/s)?
