Conceptual Problems with Velocity-Time Graphs
2. 1D Motion / Kinematics / Conceptual Problems with Velocity-Time Graphs / Problem 1
You are using high-speed motion pictures at 3200 frames/second to analyze a projectile launched from a toy gun at a nearly vertical angle. The projectile has 20 g and is 5 cm long. You generate the graph shown below using data from the motion pictures. From the graph, when is the acceleration of the projectile zero?
