3/7/24, 8:48 PM 2.1.2.1 2 Two Dimensional Problems: Mechanics, Heat, & Sound - HS - Wilkes, Deborah 2.1.2.1 2 Two Dimensional Problems e Due Oct 12, 2023 at 11:59pm Points 11 Questions 11 Available Oct 3, 2023 at 12am - Oct 27, 2023 at 11:59pm Time Limit None Allowed Attempts Unlimited Instructions In this activity, you will introduce problem-solving strategies for projectiles launched horizontally and at angles. Before you begin, you'll need one meter stick, one stopwatch, and one ball. As you work through the problems consider the following Guiding Questions: 1. What are the advantages of breaking vectors into vertical and horizontal components? 2. What happens to the velocity in the x-direction as the projectile moves? 3. What happens to the velocity in the y-direction as the projectile moves? 4. What is the maximum height the projectile reaches dependent on? 5. What is the range of the projectile dependent on? 6. What happens to the projectile at its highest point? How do you know? You will be asked to submit a photo of your work at the end of this assignment.
