Unformatted text preview: by a motor and pulley system as shown. The static coefficient of friction μ s =0.6 and the kinetic coefficient of friction μ k =0.4. (a) What cable tension is needed to start the initially stationary crate sliding up the inclined plane? (b) What is the acceleration of the crate if the tension determined in (a) is maintained. (c) The motor is capable of a maximum cable retraction rate of 4m/s. How far will the crate travel up before the maximum retraction rate is reached? =30°...
