1. Cyclist Motion and Work-Energy: Using the work-energy principle to calculate the speed of a motorcyclist moving at a constant speed with friction and resistance forces. 2. Impulse and Energy: Determining the impulse received by a particle and calculating changes in its velocity and direction after receiving an impulse. 3. Work-Energy Principle on Inclined Planes: Applying work-energy principles to find the speed and work done against friction as a particle moves up a ramp. 4. Kinetic Energy and Impulse: Analyzing kinetic energy loss during a collision, calculating the speed of particles, and interpreting the results using the coefficient of restitution. 5. Equilibrium of Lamina and Tension: Finding the center of mass of a lamina with added masses, and determining the tension in a string for a lamina in equilibrium. 6. Projectile Motion and Energy: Solving for distances, velocities, and angles in projectile motion problems using energy conservation and kinematics principles.
