    Derivation of r (radius) in terms of f (frequency)? Help please.

    2nd attempt Okay so I did rearranged an equation first to get... √ar = v and inserted it into the equation: F=mv^2/r and got... F=m*(√ar^2)/r = m*a*r/r = ma 3rd attempt: v = 2πr/T √ar = 2πr/(2πr/v) √ar = v ? (Cancelled itself out) The wrong...

    Derivation of r (radius) in terms of f (frequency)? Help please.

    okay, so the whole situation from what I've been told by my teacher is that we are deriving an equation for the radius in terms of frequency for a "rotor machine" aka the type of amusement rides that spin so fast that people are pushed against the walls and can't move. That is all the info that...

    Derivation of r (radius) in terms of f (frequency)? Help please.

    Okay, so the job I need to do is derive an equation for the radius of an object in terms of its frequency. These are the equations that we are allowed to use: v(Linear velocity) = rω v=2πr/T ω (angular velocity)=2πf f (frequency)= 1/T (time period) T= 2πr/v a (centripetal...
