2.1 Draw a labelled force diagram which shows all the forces acting on the block.
2.2
Calculate the gravitational force of the block when the force in the rope is 8 N.
Activity 3:
A block, of mass 20 kg, is pulled upwards by force F along a plane indine at 30° to the horizontal. It
accelerates along the incline plane at 2 m-s'. The surface of the incline exerts a friction forc
e on the
block.
3.1
Draw a diagram showing all the forces acting on the block (force diagram) as it move up the
incline. Also draw a free-body diagram for the block. Represent the forces on the Cartesian
plane and resolve the gravitational force into components.
Calculate the component of the gravitational force exerted on the block parallel to the
Incline
3.2
3.3
Calculate the normal force.
3.4
Calculate the friction force If the magnitude of is equal to 200 N.
3.5
Calculate the coefficient of kinetic friction for the block.​
