What is true about acceleration when carrying a passenger on a motorcycle?

When carrying a passenger on a motorcycle, it will take longer to accelerate and slow down due to the increased weight. The added weight affects the motorcycle's overall mass, resulting in a greater inertia that must be overcome to gain speed or come to a stop. This means that both acceleration and deceleration require more time and distance compared to riding solo, as the engine must work harder to move the additional weight. This principle is a fundamental aspect of physics regarding mass and motion, known as Newton's second law of motion, which states that the force required to accelerate an object is proportional to its mass.

While certain motorcycles may have more powerful engines that can mitigate this effect to some extent, the general rule of thumb is that carrying more weight leads to longer acceleration and braking times, making option B the most accurate statement concerning the effects of carrying a passenger on a motorcycle.
