Shooting star said:Frictional force = centripetal force. Assume some m for mass of car. Write the eqn.
Shooting star said:The car is moving on a circular curve, and so there must be a centripetal force acting on it. The only force that prevents the car from flying off is the force of friction between the wheel and the road, acting inward.
Frictional force F = mv^2/r. Also, F = kN = kmg, where k is co-eff of friction. Can you do it now? Remember, s = r*theta.
The purpose of finding the minimum and maximum speed is to understand the range of speeds that a certain phenomenon or process can occur at. This information can help scientists make predictions and draw conclusions about the behavior of the system being studied.
The minimum and maximum speed can be determined through various methods such as direct measurement, calculations based on known equations, or through data analysis using graphs and other visual representations.
Measuring both the minimum and maximum speed is important because it provides a more complete understanding of the behavior of a system. The minimum speed can represent the slowest possible speed at which the system can operate, while the maximum speed can show the upper limit of the system's capabilities.
There are several factors that can affect the minimum and maximum speed of a system, such as external forces, temperature, pressure, and friction. Additionally, the design and composition of the system itself can also impact its speed range.
Knowing the minimum and maximum speed can be beneficial in various real-world situations, such as designing and optimizing machinery, predicting natural phenomena, and understanding the capabilities of certain technologies. It can also aid in safety measures and risk assessments in industries such as transportation and energy production.
