Question
On a table that is frictionless lies a block that is 3.5 kg, which is connected to another hanging block of 5.0 kg. The string and pulley both have negligible masses. The block that is hanging will fall a distance, y, of 0.1m if released.
What is the work done by gravity on the two-block system?
What is the work done by the normal force on block on table?
What is the work done by tension on the block on the table? Please provide answer in the form of an algebraic expression.
Please state if the work done by tension by the hanging block. Is it zero, negative, or positive?
Please state the net work done on the hanging mass as an algebraic expression?
What will be the speed of the hanging block after falling a distance, y?
What is the tension on the string?
Transcribed Image Text:The diagram depicts a simple pulley system involving two weights and a pulley.
- **Masses**: The system includes two masses, labeled \( m_1 \) and \( m_2 \).
- \( m_1 \) is positioned on a flat surface, indicating it is subject to friction with this surface.
- \( m_2 \) is suspended vertically and hangs down from the pulley.
- **Pulley**: There is a pulley located at the edge of the surface where \( m_1 \) rests.
- The pulley is shown as a small circle and acts to redirect the tension force in the rope connecting the two masses.
- **Rope**: A rope or string connects \( m_1 \) and \( m_2 \) via the pulley.
- The diagram assumes the rope is massless and inextensible.
- **Surface**: The horizontal surface is depicted with hatch lines, suggesting it provides some frictional force affecting \( m_1 \).
This setup is a classic example used in physics to illustrate concepts such as tension, friction, gravitational force, and Newton's laws of motion.

Hints: The question is very similar to the question of a piano sliding down an incline discussed in class. However, here the object is pushed up the incline. The forces Fn = mgcos(0), and Fp = mgsin(0), so don't spend time getting these using Newton's 2nd law. Also, the weight is W = mg. c.
