I appreciate your time put towards this question. Will give impeccable rating.

a] If you use the table and the box as your system,

change in kinetic energy of the system= 1/2 m [vi2- vf2] =1/2 *6.5 [2.72-02] = 23.69 J

b] If you use the table and the box as your system,

change in thermal energy energy of the system=16.6 J

c] If you use the table as your system,

change in kinetic energy of the system= 1/2 m [vi2- vf2] =1/2 *6.5 [02-02] = 0J

d] If you use the table as your system,

change in thermal energy of the system= 16.6J

e] If you use the table as your system,

work done by friction on the system= 0.81*23.69= 19.2 J

f] If you use the box as your system,

change in kinetic energy of the system= 1/2 m [vi2- vf2] =1/2 *6.5 [2.72-02] = 23.69 J

g] If you use the box as your system,

change in thermal energy energy of the system=16.6 J
