QUESTION 6 Suppose the car was on the same frictionless track as in O5. but the bank angle changed from 30 degrees to o degrees ie, the track is entirely horizontal). In that case, which statement o the (stable and constant) velocity would increase relative to the previous question. s true? the normal force

In the example shown, if the track radius is 7 meters, what is the velocity of the mass?
300
O The velocity is zero (since the force diagram is closed)
O Need to know the masss of the car to obtain a numerical answer
O 6.29 m/s
O 3956 m/s
O 2.51 m/s
