How much work was done on the book

Reference no: EM13326762

A 1.55kg book is sliding along a rough horizontal surface. At point A it is moving at 3.31m/s , and at point B it has slowed to 1.41m/s .

a. How much work was done on the book between A and B?

b. If -0.690 J of work is done on the book from B to C, how fast is it moving at point C?

c. How fast would it be moving at C if 0.690 J of work were done on it from B to C?
