1. The problem statement, all variables and given/known data Consider the radius of the Earth to be 6.38×106 m. What is the magnitude of the centripetal acceleration experienced by a person (a) at the equator and (b) at the North Pole due to the Earth's rotation? 2. Relevant equations a = V^2 / r 3. The attempt at a solution I drew a diagram of what the problem describes but how do you get the acceleration without knowing the velocity?? Would it have something to do with angular speed??
