1. The problem statement, all variables and given/known data A flea jumps by exerting a force of 1.20x10-5 N straight down on the ground. A breeze blowing on the flea parallel to the ground exerts a force of 0.500x10-6 N on the flea. Find the direction and magnitude of the acceleration of the flea if its mass is 6.00x10-7 kg. Do not neglect the force of gravity. 2. Relevant equations F = ma F= sum of Fx + sum of Fy weight = mg 3. The attempt at a solution I figured the normal force exerted on the flea is flea's weight plus the force it exerts on the ground when it jumps. So, I used weight = mg to find the flea's weight and added it to 0.500x10-6N which equaled 1.79x10-5N. I then thought the only horizontal force was the force of the wind so that's what the sum of Fx equals. The sum of Fy equals the normal force minus the weight of the flea (which is 5.88X10-6N). I then added Fx and Fy, which equals 1.25x10-5N, to get F and set it equal to ma. I then divided 1.25x10-5N by the mass of the flea to get the acceleration. Is this right? The magnitude of acceleration I got seems high (20.8 m/s^2). Also, how do I determine the direction of acceleration?
