Super Mаriо is sliding dоwn а hill in оrder to defeаt a pair of Goombas as shown below. As he slides down, he picks up speed, accelerating down the incline at a steady 4.7 m/s2.     a)  What is the coefficient of kinetic friction between Mario and the hill? b)  Suppose the coefficient of static friction between Mario and a similar hill is 20% larger than the coefficient of kinetic friction found in part a). At what angle would the hill need to be inclined so that Mario slides down it at a constant speed? c)  If Mario has a mass of 54 kg, what is the force of static friction acting on him for part b)?
