A metal block, placed on a rough surface, is attached to a spring and is given an initial displacement of 10 cm from its equilibrium position. It is found that the natural time period of motion is 1.0 s and that the amplitude reduces by 0.5 cm in each cycle. Find (a) the kinetic coefficient of friction between the metal block and the surface and (b) the number of cycles of motion executed by the block before it stops.

Hi, please solve this problem. Thank you very much
Transcribed Image Text:15. A metal block, placed on a rough surface, is attached to a spring and is given an initial displacement of
10 cm from its equilibrium position. It is found that the natural time period of motion is 1.0 s and that the
amplitude reduces by 0.5 cm in each cycle. Find (a) the kinetic coefficient of friction between the metal
block and the surface and (b) the number of cycles of motion executed by the block before it stops.
