Question

a boat moving North in a river at 3m/s, while the current in the river moves South at 1m/s. How will the boat be affected if it enters a part of the river where the current is moving south at 2m/s?

Answer 1

When the boat enters a part of the river with a current of 2m/s south, its overall velocity will be 1m/s north.

Step-by-step explanation:

When the boat enters a part of the river where the current is moving south at 2m/s, it will be affected by the combined effect of its own velocity and the current. The resultant velocity of the boat can be calculated by subtracting the velocity of the current from the velocity of the boat.

The boat's velocity is 3m/s north and the current's velocity is 2m/s south. When we subtract the current's velocity from the boat's velocity, we get a resultant velocity of 1m/s north.

So, when the boat enters the part of the river with a current of 2m/s south, its overall velocity will be 1m/s north.
