A car moves on a flat circular track of 200 m radius with a constant speed of 20 if the car weighs 400 kg, what is the centripetal force acting on the car ?

An engineer is trying to determine the speed at which a car can travel around a curved race track without using any friction, Assume the car does not move up or down the incline and completes a horizontal circle. Complete all calculations under these circumstances. Hint: Use the variable m for the mass of the car, it will cancel! number of forces in plane: centripetal force: 340m Are all forces balanced? 160 What is the magnitude of the centripetal acceleration? unit At what speed does the car need to travel? unit finalize check answers cannot be determined (after completing ALL problems) Unit 10: circular motion, challenge Desmos Scientific Online Calculator hp esc HAAR @ #3 2$ & 96

Which statement below is incorrect with regard to curved roads? Racetracks have banked turns so cars do not have to slow down too much when navigating them Given several turns of the same radius, made of the same material but at different bank angles, the one which could be navigated at the highest speed would the one with the steepest bank. 4 wheel drive allows one to drive faster around turns in the winter If made of the same material and under the same conditions, a banked curve can always be navigated at a higher speed than a flat curve of the same radius. A banked turn can be navigated safely even if completely covered in ice

A child sitting 1.90 m from the center of a merry-go-round moves with a speed of 2.15 m/s - Calculate the centripetal acceleration of the child. - Calculate the net horizontal force exerted on the child. (mass = 34.5 kg)
