A block is set into motion up an inclined plane (30° ) with an initial speed of 8.0 m/s. There is friction between the block ant the plane. The block comes to rest after traveling 4.8 m along the plane. V = 8 m/s What is the value of the coefficient of friction µ? HINT: remember that the friction force is given by f = µN = µ = Ń thus because both f and the N are proportional to the mass of the block m, m cancels out and you don't need it to find u. Thus you wont be able to find a value for f or N alone, so find your acceleration first, then an equation for u that is independent of m.
