davidbbell3@cmail.carleton.ca CSAS: 4th Floor MacOdrum Library Activity #2: Position, Velocity, and Vectors! For the following questions, each student will be given 3 minutes to think about, and attempt the problem. When the time is up, they will get 2 minutes to discuss the problem with their partner. It will then be opened up to a class discussion about how to solve the problem. Scalar Value: Vector Value: 1) Identify the following actions as either a scalar, or vector value: A car travelling at 66 km/hr down the highway A person walking north at 0.5 m/s A dog running A cat riding up in an elevator at 1 m/s 2 minutes of time pass as we answer these questions 125 L of water exist in a tank The temperature of a backyard is recorded at 15 degrees Celsius Usain Bolt sprints a 100-metre dash towards the finish line A 200lbs weight sits on the floor An astronaut rides in a spaceship accelerating towards the ISS
David Bell CSAS: 4th Floor Library 2) Cam drives from Carleton University to Renfrew in 1 hour. Renfrew is about 98 kilometres from Carleton. What is his average velocity in km/hr? What is it in m/s? 3) It takes Chris 3 hours to complete his trail hike in Algonquin Park. His average velocity for the hike is 1.3 m/s. How long is the trail? (In other words, what is his displacement?) 4) Megan is skiing. She starts at the top of the hill at rest, and allows gravity to do the work pulling her down. When she reaches the bottom of the hill, she is travelling at 10 m/s. If her acceleration was 0.16 m/s2, how long did the trip down the hill last? 5) Joe is driving a boat across a lake. His top speed is 18 m/s in the middle of the lake, but then he begins to slow down uniformly as he moves towards the dock that is 1.2 kilometres away. By the time he reaches the dock, he has come to a complete stop. What is the acceleration? (Keep in mind axis maybe draw a diagram). 6) Sarah stands on a ledge and throws a ball straight up into the air. 6.5 seconds later, the ball lands on the ground. The distance between the ball and Sarah s hand is 17.89 metres. What was the ball s initial velocity? What was its final velocity? (Remember! Acceleration due to gravity is 9.81 m/s2 towards the Earth).
Activity #3: Vector Addition and Subtraction! A problem will be presented on the board. The board is divided into 4 sections: Prerequisite knowledge, mathematical steps, narrative of the steps, and additional sample problem. One student will fill out section 1 on the board. Then, two students will simultaneously complete section 2 and 3 on the board. Lastly, another student will complete the 4th section. We will then have a group discussion about the answers. Prerequisite Skills Solution Steps Mistakes I Made Helpful Hints
1) Vector A is 13cm long, and exists at 45 degrees above the positive X axis Vector B is 14 cm long, and exists at 65 degrees above the positive X axis If A + B = C, find C by the tail-to-tip method (graph will be drawn on board in workshop) 2) A man is on a hiking trip in Alaska. His trip can be represented by two vectors. Vector A represents a 5 km section, travelling 80 degrees North of East Vector B represents an 8 km section, travelling 45 degrees North of East Find the man s net displacement by components method (graph will be drawn on board in workshop) 3) Brad is driving a car. First, he travels at 33 m/s, 45 degrees North of East (Vector A). He then slows down to 21 m/s, and turns to 30 degrees South of East (Vector B). If A + B = C, Find vector C by components method (graph will be drawn on board in workshop)
