A 5.0 kg block rests on a smooth inclined plane that makes an angle of 30° with the horizontal. The block is attached to a light inextensible rope that passes over a frictionless pulley at the top of the incline and is connected to a hanging mass M. The rope is parallel to the plane. The kinetic coefficient of friction between the block and the plane is unknown. When the system is released the block moves up the plane with constant speed and the tension in the rope is measured to be 30 N. Using the force diagram provided, answer the following:

Question Parts

( a )
Determine the coefficient of kinetic friction (µₖ) between the block and the plane.
( b )
Find the mass M of the hanging weight.
( c )
If the hanging mass is increased to 8.0 kg, determine the acceleration of the block up the plane (assume the coefficient of kinetic friction found in part a remains unchanged).
