Projectiles Launched at an Angle Phet Activity Objectives . Create and solve for the horizontal distance a projectile will travel given the height of the canon, angle launched, and the initial velocity Create your own unique problem by choosing a set of initial conditions to solve for an unknown variable of your choice. . Create procedures for solving for different unknown variables. Set air resistance to zero on the simulation which can be found here: https://phet.colorado.edu/en/simulation/projectile-motion Part 1 (solving for horizontal distance given initial conditions of height, Vo, and the angle launched) 1. First create a problem/question in the INTRO page by setting Vo, the launch angle, and the height of the canon to certain values. You can zoom in and out of the screen using the +/- buttons in the top left corner. 2. Once you have your problem, write a procedure that will allow you to solve for the horizontal distance. (tip- first solve for the time in flight using one of the kinematic equations. Be very careful with signs) 3. Solve your problem and show the solution using the GRASS Method. 4. Test your calculation with the simulation to check for correctness. You can use the tools at the top of the screen to determine time, range and height. Part 2 (Solve for an unknown variable of your choice) 1. Play with the simulation to discover what type of variables can be solved for given certain initial conditions. Choose a variable to solve for other than horizontal distance. Indicate the page that is used (Intro, Lab, etc.) 2. Set up a problem/question with the minimum number of initial conditions needed to solve for your unknown variable. 3. Write down the procedure you need to use to solve your problem. 4. Solve your own problem using the GRASS method. Your submission for each part will include the problem/question with variables given, a detailed solution using the GRASS Method, and a written procedure (2-3+ steps) of how you solved the problem.
