The cable C of the pulley in Figure Q5 has initial velocity of 350 mm/s and constant acceleration of 275 mm/s ² that directed to the right. The inner radius of pulley that connected to the cable C is 80 mm while the radius of the outer pulley that connected to the load B is 115 mm.

(a) Find the number of revolution when t = 5 s.

(b) Calculate the velocity and change in position of the load B after 5 s.

(c) Determine the magnitude and direction of total acceleration of point D at inner pulley.

(d) Describe the function of double pulley in this system.
