- A spring has a natural length of 24.0 cm. If a 27.0-N force is required to keep it stretched to a length of 34.0 cm, how much work W is required to stretch it from 24.0 cm to 29.0 cm? (Round your answer to three decimal places.) W =A force of 50 N stretches a spring from an initial length of 10 cm to a length of 20cm. How much work is done to stretch the spring from an initial length of 20 cm to a length of 25 cm.A rope applies a horizontal force of 500 N to pull a crate a distance of 2 m across the floor. A frictional force of 50 N opposes this motion. What is the net work done on the crate?
