A flea jumps by exerting a force of 1.20×10^(-5) N straight down on the ground. A breeze blowing on the flea parallel to the ground exerts a force of 0.500×10^(-6) N on the flea. Find the direction and magnitude of the acceleration of the flea if its mass is 6.00×10^(-7) kg. Do not neglect the gravitational force.
