A massive steel cable drags a 20 kg block across a horizontal, frictionless surface. A 100 N force applied to the cable causes the block to reach a speed of 4.0 m/s in a distance of 2.0 m. What is the mass of the cable? I hate to ask you folks for a lot of help. But I have no idea of how to solve this problem, or of how to approach this problem. If anyone could I would love a little push in the right direction but I definitely am not asking for the answer.
