A block of mass m is initially at rest at the top of an inclined plane with a height = 4.4 m which makes and angle of θ = 17 degrees with respect to the horizontal. It is observed to be traveling at v = 0.2 m/s a distance d after the end of the inclined plane as shown. The coefficient of kinetic friction between the block and the plane is μp = 0.1 and the coefficient of friction on the road is μr = 0.2.
What is the speed of the block in m/s just after it leaves the inclined plane?
Find the distance d in meters.

Determine the range of values of P for the block to remain stationary if μs=0.33 between the 20kg block and the inclined plane.
