- Are you as strong as a horse? Purpose: To understand the concept of work and power and to calculate the power generated by yourself or a friend. Materials: A tape measure, stairs, and a stopwatch, cell phone, or wristwatch. Key Physics Concept: Power is the rate of doing work. Power can be calculated by dividing the work done by the time it takes to do the work; in this case we will do work against gravity on a stair case (you may add your power in doing pushups to test your arm power). Can you guess what your peak horsepower is? You may do the stairs one at at time or multiple stairs at a a time; whatever is most safe and efficient for you. Procedure: Observations: Analysis: Conclusions: Application: 1. Will your hp change if you performed the activity for a longer duration (for example, climbed the CN tower staircase)? In what way? Explain. 2. Research the horsepower generated by a car. How does the average person's peak power rating compare to it? How many average people would it…arrow_forwardDUE NOW.

- Kinetic energy is the energy possessed by an object by virtue of its position Select one: True Falsearrow_forwardPart II. Longer problem focused on problem solving multiple steps. This problem will be graded based on process, clarity of work, and correct answer and units. a. A spring is stretched, with a force, F = 442 lbf, along the outside of a pipe as shown with a = 53° and ẞ 69° and the coordinates of the force are (15,37,-71 ). How far does the spring stretch if the spring constant is k=67 lb/in? Hint: The force that stretches the spring is the projected force along the pipe F (x, y, z)arrow_forwardWhy will more heat be lost by the hot water than gained by the cold water? a)Calorimeter will absorb some of the heat. (Always the same amount.) b)Calorimeter will absorb some of the heat. (The greater the ΔT, the more of it will be absorbed by the calorimeter.) c)Conservation of energy does not work in calorimeters. d)We are using different amounts of hot and cold water.arrow_forward
