A $$369\mathrm{kg}$$ box is pulled $$8.00\mathrm{m}$$ up a $$30^{?}$$ frictionless, inclined plane by an external force of $$5425\mathrm{N}$$ that acts parallel to the plane. Calculate the work done by the external force. work done by the external force: Calculate the work done by gravity. work done by gravity: Calculate the work done by the normal force. work done by the normal force:
