Determine the maximum speed at which the car with mass m can pass over the top point A of the vertical curved road and still maintain contact with the road.(Figure 1) Express your answer in terms of some or all of the variables m, r, and appropriate constants. If the car maintains this speed, what is the normal reaction the road exerts on the car when it passes the lowest point B on the road? Express your answer in terms of some or all of the variables m, r, and appropriate constants.

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct
