Starting from rest, a 10.0-kg block slides 3.00m down africtionless ramp (inclined at 30.0° from the floor) to thebottom. The block then slides an additional 5.00m along the floorbefore coming to a stop. Determine
a) the speed of the block at the bottom of the ramp.
b) the coefficient of kinetic friction between block andfloor.
c) the mechanical energy lost due to friction.
