State the work-energy theorem

A : The change in kinetic energy of a particle is equal to the work done on it by the net force. R : The work-energy theorem can be used only in conservative field.

The work-energy theorem states that the change in

Identify the correct statement about work energy theorem.

Assertion :- According work energy theorem net work done on a body is equal to change in its kinetic energy. Reason :- The work energy theorem is independent of Newton's second law.

Asseration : Work-energy theorem can be applied for non-inertial frames also. Reason : Earth is a non-inertial frame.

You are reshelving books in a library. You lift a book from the floor to the top shelf. The kinetic energy of the book on the floor was zero and the kinetic energy of the book on the top shelf is zero, so no change occurs in the kinetic energy even though you did some work in lifting the books. Is the work-kinetic energy theorem violated?

A small blockofmass 'm' is released from rest at the top of a rough inclined plane as shown The coefficient of friction between the block and inclined plane is 'mu' Using work-energy theorem, find the speed of block as it passes the lowest point.
