View Policies Current Attempt in Progress Multiple-Concept Example 5 reviews many of the concepts that play a role in this problem. An extreme skier, starting from rest, coasts down a mountain that makes an angle of 29.7° with the horizontal. The coefficient of kinetic friction between her skis and the snow is 0.156. She coasts for a distance of 18.8 m before coming to the edge of a cliff. Without slowing down, she skis off the cliff and lands downhill at a point whose vertical distance is 4.24 m below the edge. How fast is she going just before she lands? Number i eTextbook and Media Save for Later Units Attempts: 0 of 5 used Submit Answer
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.]
A 3200 kg coaster car rolls along the frictionless track shown. To safely make it through the loop there is a minimum speed the coaster must have at the top of the loop. At this speed the normal force of the track pushing downward on the coaster is zero. The radius of the circular loop is 14.1 meters. At the top of the loop of radius 14.0 m the force of gravity is the only force acting on the coaster. What is the magnitude of the coaster's acceleration at the top of the loop?
