UNIT 1 Kinematics 1.M Projectile Motion NAME DATE Scenario A rock is thrown horizontally with speed v from the top of a cliff of height H, as shown in the diagram to the right. Using Representations PART A: On the diagram, choose a location for a horizontal and vertical origin. Label your choice with x = 0 and y = 0 on the diagram. Choose a horizontal and vertical positive direction and label those directions on the diagram using arrows. Quantitative Analysis PART B: Identify an equation that can be used to solve for the time it takes the rock to hit the ground. Write the equation below. (If you're having trouble finding the right equation, refer to your notes, your textbook, or the AP Physics 1 equation sheet.) Ay = Kot + 1/2axt PART C: Rearrange the equation you wrote above in Part B to solve for the time it will take the rock to hit the water. Your final equation should only contain given variables and physical constants. (H, v, and physical constants as necessary). Ay = Viot + / axt ? - V x otu t = PART D: Identify an equation that can be used to solve for the horizontal distance between the bottom of the cliff and the place where the rock lands. Write the equation below. PART E: Rearrange the equation you wrote above in Part D to solve for the horizontal distance D between the bottom of the cliff and the place where the rock lands. Answer in terms of H, v, and physical constants as necessary. D =
