Question

A boat moving north in a river at 3 m/s while the current in the river move south at 1 m/s. How will the boat be affected if it enters a pet of the river where the current is moving south at 2 m/s

Answer 1

The boat will be affected by the change in the current. When the boat enters the part of the river with the current moving south at 2 m/s, the boat will be pushed south at a speed of 5 m/s (3 m/s + 2 m/s). This is because the force of the current is stronger than the force of the boat, so the boat will be pushed in the direction of the current.
