36. Determine the acceleration of the system shown in Figure 2, assuming the blocks start from rest and the coefficient of kinetic friction is 0.20. 37. An 800 kg sport car accelerates at 70 m/s2on a highway when its engine produces a force of 60 000 N. Calculate the coefficient of kinetic friction between tires and road surfaces. Sept 2015

38. A 1100 kg car travels on a straight highway with a speed of 30 m/s. the driver sees a red light ahead and applies the brakes until the car stops, which exerts a constant braking force of 4000 N. Compute the deceleration of the car.
) 39. Figure 3 shows an object M which has a mass of 10 kg. If the inclined surface is rough with the coefficient of friction between the object and the incline plane is 0.2. As the object M slides down the incline: i. Sketch all the forces acting on object M, ii. Calculate the magnitude of acceleration of object M.

40. Block A of mass 30 kg is at rest on a 40° inclined rough plane with coefficient of friction 0.15. The block is attached by a light string to block B with a mass of 40 kg, as shown in Figure 3. i. Compute the tension in the string.
ii. Draw the free body diagram for block A and block B. iii. Determine the frictional force exerted on block A.
