Question

The propeller exerts a force on the air, pushing it backwards behind the boat. At the same time, the air exerts a force on the propeller and consequently on the airboat. Forces always come in pairs of this kind, which are formalized in the next section as Newton's third law of motion. The negative answer for the acceleration in part (c) means that the airboat is slowing down. What other forces act on the airboat? (Select all that apply.) the downward force of gravity on the boat the mass of the boat and passenger times their acceleration the velocity of the boat and passenger the upward force of the water on the boat the downward force of the water on the boat

Explanation / Answer

The other forces acting on the airboat

(i) The downward force of gravity on the boat.( weight is always acting downwards)

(iv) The upward force of the water on the boat( Buoyant force on the boat acting upwards)
