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 ms. 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.
6.2 Calculate the component of the
gravitational force exerted on the block
parallel to the incline.
(2)
6.3 Calculate the normal force, Fexerted
by the surface on the block on the incline. (2)
6.4 Calculate the friction force, F, if the
(5)
magnitude of force F is equal to 200 N.
6.5 Calculate the coefficient of kinetic
(3)
friction,
for the block.
