A solid cylinder rolls without slipping down an incline starting from rest.At the same time a box starts from rest at the same altitude and slides down the same incline with negligible friction.Which arrives at the bottom first?
A)the box
B)the cylinder
C)Both arrive at the same time.
D)It is impossible to determine.

The box arrives at the bottom first because it only converts its potential energy into translational kinetic energy, whereas the cylinder converts its potential energy into both translational and rotational kinetic energy, resulting in a slower descent due to the energy distribution.
