Final answer:
The driver of a motor boat moving at a constant speed of 10 m/s is experiencing constant velocity, meaning there is no change in the speed or direction of the boat.
Step-by-step explanation:
If the driver of a motor boat is moving at a constant speed of 10 m/s, this implies that the velocity of the motorboat is unchanging in both magnitude and direction. Therefore, the correct answer to the question would be b) Constant velocity.
In the absence of additional forces acting on the boat, such as wind or currents, a constant speed indicates there is no acceleration or deceleration occurring when the boat is moving at a sustained rate of 10 m/s.
Acceleration would imply a change in velocity, either an increase or decrease in speed or a change in direction. Deceleration specifically refers to the reduction in speed, and zero velocity would mean the boat is stationary.
However, given the information provided, the boat is neither accelerating, decelerating, nor at rest; it is traveling at a steady speed.
