Answer

The average power of the machine's force on the package is $~~8.4~W$

Work Step by Step

In part (a) we found that the work done on the package by the force is $~~101~J$ We can find the average power of the machine's force on the package: $P = \frac{W}{t} = \frac{101~J}{12~s} = 8.4~W$ The average power of the machine's force on the package is $~~8.4~W$
