A 1 kg physics book lying on a 20 degree incline isattached to a 500g coffee cup. The book is given a push up theslope and released with a speed of 3m/s. The coefficients offriction are: static friction μ = 0.5 and kinetic frictionμ = 0.2.
a. How far does the book slide?
b. At the highest point, does the book stick to the slope, ordoes it slide back down?
