(c) Now assume that the block on the incline plane is sliding upward. The coe cient of kinetic friction between the block and the incline surface is k. Find the magnitude of the acceleration of the block on the inclined plane, a. x1. Express your answers in terms of some or all of the variables m. 1, m. 2, , k. and the acceleration of gravity g.
Answer: (a) The acceleration of the mass is given by the horizontal component of the tension; the vertical component of the tension is equal to the weight. 15 Example 4-1b: Sliding Down An Incline A box of mass m is placed on a smooth (frictionless!) incline that makes an angle θ with the horizontal.
