A airplane flies in a circle of radius 1.0 km at a constant speed of 1248 m/s. What is the centripetal acceleration of the airplane in km/s/s?
would the centripital accel be = (to v^2/r) or (1248^2)/1 which would be 1557504 km/s/s
Yes, but it seems as if there is only one mass the mass of the boy i didnt know wher the second mass would come from that's why it staryed me away from this equation but i wasnt sure what else i coudl use
A boy of mass 41 kg rides on a playground merry-go-round at a speed of 2.0 m/s. and has to hold on with a force of 79 N to keep from flying off. What is the radius of the merry-go-round?
