Question

A 5kg block at first has a speed of 1.5m/s at the top of a 30? incline, and slides a distance of 5.0m down incline in 1.75s.

(a)Find magnitude of the acceleration of block.

(b)Illustrate a free-body diagram for the block. You might not neglect friction. Utilize a coordinate system with the x-axis pointed down the incline, and decompose all vectors into x and y components.
Label everything.

(c)Find components of the gravitational force in the given coordinate system.

(d)Find normal force and the force of kinetic friction.

(e)Find coeficient of kinetic friction.

(f)What is final speed of the block?
