In 1991, a lobster with a mass of 25.0 kg was caught off the coast of Nova Scotia, Canada. Imagine this lobster involved in a friendly tug of war with several smaller lobsters on a horizontal plant at the bottom of the sea. Suppose the smaller lobsters are able to drag the large lobster a distance of 3.4 m reaching a maximum speed of 0.450 m/s. If the lobster is initially at rest, what is the magnitude of the net force applied to it by the smaller lobsters? Assume that friction and resistance due to moving through water are negligible.
