A rope applies a horizontal force of 208 N to pull a crate a distance of 1.91 m across the floor. A frictional force of 154 N opposes this motion.
(a) What is the work done by the force applied by the rope?
(b) What is the work done by the frictional force?
What is the total work done on the crate?
(a) 208 * 1.91 Joules
(b) -154 * 1.91 Joules
either add answers to a and b or do
