a motor traveling at a constant speed is just able to completely go round a vertical circular track of radius 8m The total mass of motor is 210kg
i)Compute the angular velocity at the top of the track
ii)compute the maximum force on the track
Homework Equations
The Attempt at a Solution
i know that when the motor is at the top of the track the formula should be Fn+m(v^2/r) = mg
but i just can't found v.
