1. The problem asks which scenario results in the most total work done. 2. Work is defined as the force applied times the displacement in the direction of the force: $$W = F \times d$$. 3. Important rule: If there is no displacement in the direction of the force, the work done is zero. 4. Analyze each option: a. Carrying a backpack down the hall: The force (lifting the backpack) is vertical, displacement is horizontal, so work done by lifting force is zero. b. Holding a bass drum while waiting: No displacement, so work done is zero. c. Hanging from a swing set: No displacement, so work done is zero. d. Lifting a cheerleader to the top of a pyramid: Force is upward, displacement is upward, so work is positive and nonzero. 5. Therefore, option d results in the most total work done. Final answer: d lifting a cheerleader to the top of a pyramid
