State the principle of conservation of linear momentum. What is meant by impulse of force? Write its formula. What is meant by couple? Write any two examples. Define torque and center of mass. A metal ball falls from a height of 1m on a steel plate and jumps up to a height of 0.4m. Find the coefficient of restitution.
Understand the Problem
The question is asking about various physics concepts such as conservation of momentum, impulse of force, couple, torque, center of mass, and the coefficient of restitution. These topics relate to mechanics in physics.
Answer
Coefficient of restitution is 0.632.
The coefficient of restitution is 0.632.
Answer for screen readers
The coefficient of restitution is 0.632.
More Information
The coefficient of restitution is a measure of how much kinetic energy remains after a collision, with a value of 1 indicating a perfectly elastic collision.
Tips
Common mistakes include not considering all forces in the system or misapplying the impulse-momentum theorem. Ensure units are consistent when calculating impulse.
