In the diagram the red block has a mass of 9 kg, the blue block has a mass of 10 kg, & the pulley has a mass of 6 kg. Treat the pulley as a hollow cylinder, assume the string remains taut the entire time, and assume no thermal energy is generated. Find out how fast the blue block will be going when it hits the ground if it was released from rest 90 cm above the ground.

In the diagram the red block has a mass of 9 kg, the blue block has a mass of 10 kg, & the pulley has a mass of 6 kg. Treat the pulley as a hollow cylinder, assume the string remains taut the entire time, and assume no thermal energy is generated. Find out how fast the blue block will be going when it hits the ground if it was released from rest 90 cm above the ground.

The image depicts a classic physics problem illustrating a pulley system. 

**Description:**

- The system consists of two blocks connected by a rope that passes over a pulley.
- **Pulley:** The pulley is shown as a black circle at the top right corner. It allows the rope to change direction.
- **Block on Horizontal Surface:** On the left, a red block rests on a horizontal surface. This block can slide.
- **Hanging Block:** On the right, a blue block hangs vertically.

**Explanation:**

- The red block on the left represents a mass that is subject to sliding friction on the horizontal surface.
- The blue block on the right is suspended in the air, contributing gravitational force to the system.
- The pulley enables the transfer of the gravitational force from the blue block to move the red block horizontally.
- This setup is often used to demonstrate concepts like tension, friction, and Newton's second law of motion.
