Sir, when I say the last question I mean C. the problem is not of who are. "they". the problem lies in the exercise. In the end, the resistance force was listed as a positive force when Newton's second law was applied. the sum of forces = m a / F resit = m.a. whereas it should be written as -...

regarding the last question. I know that resistance is a negative force because it goes in the opposite direction to the movement of the boat. So whenever, I want to apply Newton's 2nd law of motion: the sum of forces = m a I should write - F resit = m.a. However, they have considered the...
