Question

a boats engine provides a forward thrust of 2000 n, and the water resistance (drag) against the hull is 1500 n. what is the net force acting on the boat in the direction of motion?

Explanation:

Step1: Define forces

Let the forward thrust \(F_{thrust}=2000\ N\) (positive direction) and drag \(F_{drag} = 1500\ N\) (negative direction).

Step2: Calculate net force

Net force \(F_{net}=F_{thrust}-F_{drag}\).
Substitute values: \(F_{net}=2000 - 1500\).

Answer:

\(500\ N\)
