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