QUESTION 2 The two blocks are attached to one another by a massless string that is wrapped over a frictionless pully. A force F is applied to the left of the bottom block at an angle of 30° with the floor. Assume that the coefficient of kinetic friction between all the surfaces is 0,15. 2.1 2.2 2.3 2.4 F 30⁰ 3kg 6 kg Draw a labelled free-body diagram of the 6 kg-block. Calculate the magnitude of the frictional force between the two blocks. Find the component of F necessary to move the blocks at a constant speed. Calculate the magnitude of F. (5) (3) (6) (3) [17]​
