Question

A machine carries a 3.0 kg package from an initial position of di = (0.50 m) + (0.75 m) + (0.20 m) at t = 0 to a final position of df = (7.30 m) + (11.0 m) + (7.20 m) at t = 14 s. The constant force applied by the machine on the package is F = (2.00 N) + (4.00 N) + (6.00 N) .
(a) For that displacement, find the work done on the package by the machine's force.
J

(b) Also, find the power of the machine's force on the package.
W

Answer 1

(a)96.6J

(b)6.9W
