In the figure a block slides along a track from one level to a higher level, by moving through an
intermediate valley. The track is frictionless until the block reaches the higher level. There a frictional
force stops the block in a distance d. The block's initial speed vo is 6m/s. the height difference his
1.1 m and the coefficient of kinetic friction p is 0.6. The value of dis :

(A) 1.71 m
(B) 1.17 m
(C) 7.11 m
(D) 11.7 m

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.
