A helicopter of mass M is lowering a truck of mass m onto the deck of a ship. In the first case the helicopter and the truck move downward together (the length of the cable remains constant). The tension in the cable is T 1 ​ when their downward speed is decreasing at a rate of g/10 ​ . In the second case when the truck gets close to the deck, the helicopter stops moving downward. While it hovers stationary, it lets out the cable so that the truck is still moving downward. The truck is moving downward with a speed decreasing at the rate of g/10 ​ , tension in the string is now T 2 ​ . What is ratio T 1 ​ /T 2 ​ ?
