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...

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...

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...
