  1. AFrom the top of a lighthouse, 100 m high, the angle of depression of a boat is ^ -1 ((5)/(12)).What is the distance
  2. BFrom the top of a lighthouse, 100 m high, the angle of depression of a boat is ^ -1 ((5)/(12)).What is the distance
  3. CFrom the top of a lighthouse, 100 m high, the angle of depression of a boat is ^ -1 ((5)/(12)).What is the distance
  4. DFrom the top of a lighthouse, 100 m high, the angle of depression of a boat is ^ -1 ((5)/(12)).What is the distance

Correct answer

A. From the top of a lighthouse, 100 m high, the angle of depression of a boat is ^ -1 ((5)/(12)).What is the distance

Step-by-step solution

In the beginning due to gravity pull, the lead shot will be accelerated and hence will move, with increasing velocity for some time When the viscous force balance the gravity pull, then the shot will move with constant velocity. As in the beginning, the velocity of shot is not fully linear with the effective distance covered by the shot.
