Question

question 5.a
which of the following best describes the forces acting on the ship?
a. the forward force of the engines is greater than the backward force of the water resistance.
b. the forward force of the engines is equal to the backward force of the water resistance.
c. the forward force of the engines is less than the backward force of the water resistance.
d. there are no forces acting on the ship since its moving at a constant speed.

Explanation:

According to Newton's first law of motion, when an object is moving at a constant speed, the net force acting on it is zero. This means the forward force (from the engines) must balance the backward force (water resistance).

Answer:

B. The forward force of the engines is equal to the backward force of the water resistance.
