Ship and rope problem

  1. Aug 30, 2008 #1
    So this one should be simple to solve with some maths.

    There is a boat of height 15 metres (measured from sea-level) and there is a rope hanging from its deck so that the distance from the sea-level is half the third of the boat's height.

    It is given that the sea-level is rising at the constant rate of 1.75 cm/s. After how much time will the rope be wet?

    As soon as it starts raining.

    As sea level will rise, ship will also go up. The rope tied to deck will also go up and will not touch sea level.
