Final answer:
When a wheel reaches an angular speed of 9.5 radians per second, the expected behavior of the constant friction force depends on the context and conditions. Generally, at high speeds, the friction force tends to decrease to prevent excessive heat generation and wear. However, in situations where friction is necessary for maintaining motion or preventing slipping, the friction force may remain constant or even increase.
Step-by-step explanation:
Once the wheel in the previous question reaches an angular speed of 9.5 radians per second, the expected behavior of the constant friction force depends on the context and conditions. Generally, when the wheel reaches a high angular speed, the friction force tends to decrease. This is because at high speeds, the frictional force can cause excessive heat generation and wear on the wheel and the surface it is in contact with.
However, if the friction force is necessary to maintain the motion or prevent slipping, it may remain constant or even increase. For example, in situations where the wheel needs sufficient friction to maintain grip or traction, such as in a car's tires, the friction force may increase to prevent skidding.
