[QUOTE="jimmyboykun, post: 4585030, member: 490778"] [h2]Homework Statement [/h2] You are consulting for an amusement park that wants to build a new "Rotor" ride. In order to increase capacity, they would like to build a unit with a 14.2-ft diameter. The Rotor should provide a centripetal acceleration of 3g. What must be the angular speed in revolutions per minute (rpm)? [h2]Homework Equations[/h2] a(centripedal)= v^2/radius v=ωr [h2]The Attempt at a Solution[/h2] 1ft=0.3048m---> 14.2ft*0.3048m/ft= 4.33m 4.33/2= 2.16(this is the radius) 3(9.81m/s^2)= 29.43m/s^2 v^2=2.16*29.43m/s^2=63.5688 sqrtv=sqrt63.5688=7.97m/s v=ωr 7.97m/s=ω2.16 7.97/2.16=ω ω=3.69rad/s 3.69rad/s*1rev/2∏*60s/1m= 344.77rpm 344.77rpm is my final answer but I got that wrong, where did I go wrong in my calculations?
