Final answer:
The speed of hydroplaning for a non-rotating tire is represented by the equation √(9P), with option B being the correct answer. This concept is essential in understanding the physics of vehicle dynamics and safety.
Step-by-step explanation:
The equation for the speed of hydroplaning for a non-rotating tire is commonly given by √(9P), where P is the inflation pressure of the tire. The correct answer to the student's question is option B) √(9P). Hydroplaning occurs when a layer of water builds up between the wheels of the vehicle and the road surface, leading to a loss of traction that prevents the vehicle from responding to control inputs.
