A machine carries a 4.0 kg package from an initial position ofdi = (.50m)i + (.75m)j + (.20m)k at t=0 to a finalposition of df = (7.50m)i + (12.0m)j + (7.20m)k at t =12s. The constant force applied by the machine on the package is F= (2.00N)i + (4.00N)j + (6.00N)k. For that displacement, find (a)the work done on the package by the machine's force and (b) theaverage power of the machine's force on the package.
