Question: 1a. If the book is actually going 3.00 m/s, what was the coefficient of friction between the book and the ramp? 1b.How much work did friction do on the book? Given information: 1.A student does 125.0 J of work lifting a 12.0 kg book. Book lifted 1.06m high. 2.The book from info 1 is then allowed to slide down a straight ramp which makes a 26.0o angle above the horizontal, and the book reaches its original position at the end of this ramp. How fast would it be going if there was no friction? (4.56m/s)
