10. (40) A cart of mass meart 3kg that exhibits a friction coefficient of p = 0.20) is resting on a level track. On top of the cart is a mass of mtop 2kg that has a friction coefficient of 2 = 0.40 between itself and the cart. The cart is attached by a string draped over a pulley to a hanging mass mhanging that is unknown. The pulley is massless and frictionless - very expensive;) a) What max mass can be hung from the string such that the cart doesn't move? b) What max mass can be hung such that the mass on top of the cart doesn't start to slip off as the system accelerates? c) What will the acceleration be with a hanging mass of 10kg hanging? d) By isolating one part of the system, find the tension in the string for case c. 10.
