The 2.60 kg physics book shown is connected by a string to a 467.0 g coffee cup. The book is given a push up the slope (call this direction positive) and released with a speed of 2.04 m/s. The coefficients of friction are μs = 0.478 and μk = 0.227. What is the acceleration of the book if the slope is inclined at 22.1∘?
