Answer:
Step-by-step explanation:
The net force R100 refers to the net force experienced during the acceleration from 0 to 100 mph, while the average net force R60 represents the average net force experienced during the acceleration from 0 to 60 mph. To compare these two forces, we need to understand the concept of net force and how it relates to acceleration.
Net force is defined as the vector sum of all the forces acting on an object. It determines the object's acceleration according to Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Mathematically, this can be expressed as Fnet = ma, where Fnet is the net force, m is the mass of the object, and a is its acceleration.
During the acceleration from 0 to 60 mph, a vehicle undergoes a certain amount of force exerted on it to increase its speed. This force is provided by the engine and transmitted through various components such as the transmission system and wheels. As the vehicle gains speed, air resistance also becomes a significant factor opposing its motion.
When comparing the net forces R100 and R60, it can be inferred that R100 will be greater than R60. This is because accelerating from 0 to 100 mph requires a larger amount of force compared to accelerating from 0 to 60 mph. The additional force needed to reach higher speeds accounts for this difference.
Several factors contribute to this increase in required force. Firstly, as speed increases, air resistance becomes more significant. Air resistance is a force that opposes the motion of an object through a fluid medium, in this case, air. At higher speeds, air resistance increases exponentially due to factors such as increased drag coefficient and frontal area.
