The 3.90kg physics book shown is connected by a string to a 474.0g coffee cup. The book is given a push up the slope and released with a speed of 1.55m/s. The coefficients of friction are ?s = 0.514 and ?k = 0.191.
1. What is the acceleration of the book if the slope is inclined at 23.9°?
2. How far does the book slide before it has zero speed?
