Under good conditions, a car can travel at a maximum speed of vmax around a particular unbanked curve. In the aftermath of an ice storm, however, driving at that same speed will cause the car to slide off the road. Which of the statements below best describes why this is true? a. The friction force is no longer strong enough to balance the centripetal force and give the car zero acceleration. b. The friction force is needed to do negative work on the car to reduce the car’s kinetic energy. c. The friction force no longer provides a strong enough unbalanced force to change the car’s velocity quickly enough to stay on the curve. d. The car “floats” on the ice reducing the gravitational force which is what keeps the car on the road. e. [All of the above.]

How would this lab change if you used a heavier object? A lighter object? Explain your rationale for each situation. The acceleration due to gravity is a well-understood physics quantity, with respect to the surface of the Earth. It is determined with knowledge of the mass of the planet, as well as the distance from the center of the planet to a known location. As a global average, it is assumed the acceleration due to gravity is 9.805 m/s2, with slight fluctuations around the poles due to the fact the Earth is not a perfect sphere. However, this acceleration is not constant on other planets, due to their different size and mass. The purpose of this experiment is to determine the acceleration due to gravity of a falling object.
A dancer is standing on one leg on a drawbridge that is about to open. The coefficients of static and kinetic friction between the drawbridge and the dancer's foot are μs and μk, respectively. n⃗ represents the normal force exerted on the dancer by the bridge, and F⃗g represents the gravitational force exerted on the dancer, as shown in the drawing.(Figure 1). For all the questions, we can assume that the bridge is a perfectly flat surface and lacks the curvature characteristic of most bridges. Before the drawbridge starts to open, it is perfectly level with the ground. The dancer is standing still on one leg. What is the horizontal component of the friction force f⃗? (Express your answer in terms of some or all of the variables n, μs, and/or μk.) (Figure 2). The drawbridge then starts to rise. The dancer continues to stand on one leg. The drawbridge stops just at the point where the dancer is on the verge of slipping. What is the magnitude f of the frictional force now? (Express…

What is the location of the ball, and what is the magnitude of the centripetal acceleration of the ball in terms of g?
