i need help on a force question please!! 1. The problem statement, all variables and given/known data The 1.0kg physics book in the figure below is connected by a string to a 500g coffee cup. The book is given a push up the slope and released with a speed of 3.0 m/s. The coefficients of friction are us=0.50 and uk=0.20. a) How far does the book slide? b) At the highest point, does the book stick to the slope or does it slide back down? 2. Relevant equations F=mgsin(theta) F=ukmg im not too sure what equations to use cuz im kinda confused at the free body diagram. 3. The attempt at a solution F=mgsin20 = (1.0)(9.8)(sin20) = 3.35N Do I have to split the 2 objects? like draw one FBD for the cup, and one for the book? How do i do that? Please help!
