than on the sides so that the downward centripetal acceleration at the top will be greater than the acceleration due to gravi keeping the passengers pressed firmly into their seats. D B minimum Imaximum с A What is the speed, in m/s, of the roller coaster at the top of the loop if the radius of curvature there is 16.0 m and the downward acceleration of the car is 1.50 g? 24.5 What is the relationship between centripetal acceleration and tangential speed? m/s

A roller coaster contains a loop-the-loop in which the car and rider are completely upside down at the top of the loop. The radius of the loop is 16 m. What minimum speed (in m/s) must the car have at the top so that the rider does not fall out while upside down? Assume the rider is not strapped to the car. 12.53 m/s. What is the magnitude of the normal force at the top of the loop? What is the magnitude of the normal force at the bottom of the loop?

Pls help ASAP.

In 1959, Daytona Speed was added to the NASCAR racing circuit and introduced 31° banked curves for racing. This allowed stock cars to reach much higher speeds (around 200 mph) during a race. Today the steepest banked curves are found at Talladega Motor Speed Way at 33° with a turn radius of 1100 ft. The flattest track in NASCAR is Hew Hampshire Motor Speed Way with banked curves of 7° with a turn radius of 410 ft. a) Assuming no friction, what are the max speeds (in mph) without slipping toward the outer edge of the track at the Talladega and NH Motor Speedways? b) With friction (assume μs of 1.1 between the tires and the track)?
