1. The problem statement, all variables and given/known data the main question asks: "If the book is initially at rest, what is its speed after it has traveled 0.400 m up the wall?" 2. Relevant equations ∑F = m*a vf2 = vi2 + 2 * a * d , when initial velocity is 0. 3. The attempt at a solution So here's my free body diagram: and out of that FBD I got these equations: ∑Fx=N−Fcos(60)=0 ∑Fy=fk+Fsin(60)=ma I know that fk=μ(Fcos(60)) = μN Should i solve for the acceleration and then plug it in the kinematics equation to solve for final velocity? And are my equations and FBD right?
