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…

Question 11) Roger gave the following account of a roller-coaster ride: 1 tried a brand-new ride at a science centre. There's a computer screen that tells you how much the car and the people in it weigh and how high and fast you travel. You get into the car and they strap you in. The car weighs 600 kg. At the top, it moves horizontally at a speed of 1 m/s. Then you drop 30 m, make a loop into the air and finish by riding over an 8-m hill. I don't remember our maximum speed or our speed at the top of the loop, but the ride was fantastic!" Answer the following questions without taking the force of friction into consideration. Show your calculations for each question. A v=1 m/s 20 m 8 m a) What is the highest speed Roger could have attained? What is the potential energy of the roller-coaster car when it is at the top of the b) loop? c) What is the kinetic energy of the car as it passes over the top of the 8 m hill? d) What is the total mechanical energy of the system?

Statics and Principles of Moments  A seesaw that weights 45lbs and its 5m long is balanced on the fulcrum in the center.  1- Two children are sitting on opposite sides of each other on the seesaw. One child weights 50lbs and is sitting 0.7m on the left side. Where should the other child sit in order to be balanced on the seesaw if they weigh 42lbs?  2- Now, another child wants to sit on the seesaw and weighs 30lbs and is sitting 1.25m in front of them and is closer to the fulcrum. What are the CW and CCW moment of the seesaw now? What is the net moment and direction?  3- Then, a fourth child wants to play on the seesaw and is on the left side of the plank in order to bring the system to equilibrium. How much does the child weigh (Calculate the pounds of force needed in order for rebalance?)  4- Now the fourth child leaves the other three children sitting on the plank. If the three children are sitting in the same potions as they did in part b, the plank would need to move on the seesaw…
