An early submersible craft for deep-sea exploration was raised and lowered by a cable from a ship. When the craft was stationary, the tension in the cable was 6500 N. When the craft was lowered or raised at a steady rate, the motion through the water added an 1800 N drag force.
What was the tension in the cable when the craft was being lowered to the seafloor?
A box weighing 50 N rests on a horizontal surface. A person pulls with a force of 10N to the right and it does not move. In order for you to move, you need another person who pulls vertically. What is the minimum force that the other person needs to exert in order for it to move? Coefficient of static friction = 0.4
