In class, one sophisticated and expensive demonstration the class would see is where I lifted one end of the table until my book started to slide, then kept the angle fixed. Suppose the coefficient of kinetic friction was μk = 0.380, and the 1.63 kg book started sliding from rest at an angle of 42.1o. What would the speed of the book at the bottom of the 1.42 m long table?

I need a step by step please it seems everything I'm doing is wrong. Like I know the equation v2^2 = v1^2 + 2ad but how do I get v1^2?

I’ve literally sat at this for 2 and a half hours. “Just look closer” and “it’s in the question” isn’t gonna help me solve it. Doesn’t the fact that I posted it mean I can’t figure it out? Please forget it I’ll ask someone else.
