A Ferris Wheel has a radius of \(60\) feet and makes one revolution every \(4\) minutes (so you could write this as \(\frac { 1 \text { revolution} } { 4 \text { minutes} } \)or \(\frac { 1 } { 4 } \frac { r e v } { m i n } \) ). Find the linear speed in feet per minute. Round to three decimal places. Show all calculations in your written work. 

Object \( A \) has a mass \( mA \) and velocity vA. Object \( B \) has a mass equal to \( 3 mA \) . What velocity would object \( B \) have if its momentum equaled the momentum of object \( A \) ?
