What is the ideal speed to take a 100.0-m-radius curve banked at a 20.0angle?
If a car takes a banked curve at less than the ideal speed, friction is needed to keep It from sliding toward the inside of the curve (a problem on icy mountain roads).

An airplane flying at 200.0 m/s makes a turn that takes 4.0 mm. What bank angle is required? What is the percentage increase in the perceived weight of the passengers?
Why does banking a curve on a highway allow a vehicle to successfully negotiate the turn at a higher speed?
Suppose a child is riding on a merry-go-round at a distance about halfway between its center and edge. She has a lunch box resting on wax paper, so that there is very little friction between it and the merry-go-round. Which path shown below will the lunch box take s1wn she lets go? The lunch box leaves a trail in the dust on the merry-go-round. Is that trail straight, curved to the left, or curved to the right? Explain your answer.
Centripetal Force If you wish to reduce the stress (which is related to centripetal force) on high-speed tires, would you use large- or small-diameter tires? Explain.
Suppose a mass is moving in a circular path on a frictionless table as shown below. In Earth’s frame of reference, there is no centrifugal force pulling the mass away from the center of rotation, yet there is a force stretching the siring attaching the mass to the nail. Using concepts related to centripetal force and Newton’s third law; explain that force stretches the string, identifying its physical origin.
