1. The problem statement, all variables and given/known data A body is at rest at a location on the Earth's equator. Find its acceleration due to the Earth's rotations. [Take the Earth's radius at the equator to be 6400 km.] 2. Relevant equations Possible relevant equations: a=(dv/dt)*t + (v^2/rho)*n, n is the unit normal vector., F= M*m*G/(R^2(earth)) 3. The attempt at a solution If the body is at rest , then the velocity of the body must be zero. F=M*m*G/(R^2(earth))=> m*(a+g)= M*m*G/(R^2(earth)) => a+g= MG/(R^2(earth)) , M being the mass of the earth. Therefore a= MG/(R^2(earth))-g = (6.0e24)*((6.6e-11))/((6.4e6 m)^2) - 9.8 = -.0294 m/s^2. The actually answer is .034 m/s^2. What is wrong with my calculations?
