Q

How much work would be accomplished if a 15 pound box were raised to the top of a 25 foot platform?

🔍 Key Concepts

• Work = Force × Distance in physics, with consistent units • A weight in pounds acting through a vertical distance in feet gives work in foot-pounds (ft-lb) • Only the component of the force in the direction of motion contributes to the work

💭 Think About

• What force is being applied to lift the box straight up, and what is its value in pounds? • Over what exact distance (in feet) is this force applied while lifting the box onto the platform? • How do you combine that force and distance to get work, and which answer choice matches that product?

✅ Before You Answer

• Be sure you are multiplying weight (lb) by height (ft), not adding them • Confirm the units of the final result are ft-lb • Verify that you used the full platform height given in the problem, not a partial distance
