6. A block, mass 20 kg, is pulled upwards by a force F along a plane inclined at 30° to the horizontal. It accelerates along the inclined plane at 2 m.s-2. The surface of the incline exerts a friction force on the block 6.1 Draw a diagram showing all the forces acting on the block (a force diagram) as it moves up the incline. Also draw a free-body diagram for the block. Calculate the component of the (4) 6.2 gravitational force exerted on the block parallel to the incline. (2)
