Problem
A block of wood initially at rest slides down an inclined plane. Neglecting friction, the kinetic energy of the block at the bottom of the plane is:
a. all converted into heat.
b. less than its kinetic energy at the top of the plane.
c. dependent on the materials of which the block is made.
d. dependent on the materials of which the inclined plane is made.
e. equal to its potential energy (with respect to the bottom of the plane) when it was at the top of the plane.
