Problem: A 1.50 kg book is sliding along a rough horizontal surface. At point exttip{A}{A} it is moving at 3.21 m/s , and at point exttip{B}{B} it has slowed to 1.25 m/s .How much work was done on the book between exttip{A}{A} and exttip{B}{B}?If -0.750J of work is done on the book from exttip{B}{B} to exttip{C}{C}, how fast is it moving at point exttip{C}{C}?How fast would it be moving at exttip{C}{C} if 0.750J of work were done on it from exttip{B}{B} to exttip{C}{C}?
