Unit 5 Notes
... In the y direction the momentum of the cue ball and the target ball are equal in magnitude and opposite in direction. The velocities equal sin45(vcue) and sin45(vtarget) In the x direction the velocities are: cos45(vcue) and cos45(vtarget) The momentum in the x direction is conserved so: .15kg(3.00m ...

... 2. For one object, draw a free-body diagram, showing all the forces acting on the object. Make the magnitudes and directions as accurate as you can. Label each force. If there are multiple objects, draw a separate diagram for each one. 3. Resolve vectors into components. 4. Apply Newton’s second law ...

... If objects in the system are elastically deformed by the forces they exert on each other, the work done by those forces is stored as elastic potential energy. When the objects’ pre-collision shapes are restored, that elastic potential energy is reconverted into kinetic energy. So, the total kinetic ...
