A small block of mass is placed on top of a ramp at a height above a horizontal track. The ramp is frictionless. When the block is released, it slides down the ramp to point B, where it has a speed. Beginning at point B, there is a coefficient of kinetic friction between the block and the horizontal track. The block slides along the track for a distance until it comes to a stop at point C. Resistive forces other than friction can be ignored. The height is 18 cm, the distance is 22 cm, and the distance is 25 cm (the angle can be determined from and assuming a right triangle). If the mass of the block is 0.26 kg and the coefficient of kinetic friction is 0.28, what is the speed of the block at point B in cm/s?
a) Determine the speed of the block at point B.
b) Calculate the work done by friction from B to C.
c) Find the distance the block travels from B to C.
d) Determine the net work done on the block from B to C.
