One end of a 34-m unstretchable rope is tied to a tree; the other end is tied to a car stuck in the mud. the motorist pulls sideways on the midpoint of the rope, displacing it a distance of 2 m (assume the car slides forward slightly in response to this, but then become stuck again). if he exerts a force of 87 n under these conditions, determine the force exerted on the car. round your answer to one decimal place.
