A block with a mass of 12.0 kg is initially at rest at the top of a plane that is inclined at an angle of 30.0° above the horizontal. The block slides down the plane and is traveling with a speed of 1.50 m/s when it reaches the bottom. If the plane is 0.750 m long, what is the coefficient of kinetic friction between the block and the plane? please explain each step.

A block of mass m is initially held at rest at point P on an incline that makes an angle q with respect to horizontal. The coefficient of kinetic friction between the block and the incline is mk. After the block slides down the incline from point P, it starts to slide without friction up a vertical circular track of radius R. When it reaches the top of the circle, the normal force (downward) by the track to the block...
