Problem-Solving Strategy 6.1 Projectile motion problems Model Make simplifying assumptions. Visualize Use a pictorial representation. Establish a coordinate system with the x -axis horizontal and the y -axis vertical. Show important points in the motion on a sketch. Define symbols and identify what the problem is trying to find. Solve The acceleration is known: and Thus the problem becomes one of kinematics. The kinematic equations are D t is the same for the horizontal and vertical components of the motion. Find D t from one component, then use that value for the other component.
