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

![a=\frac{F_{1}+F_{2}+W}{m} \\a=\frac{1.20*10^{-5}j+(0.500*10^{-6} )i+(mg)}{m}\\a=\frac{1.20*10^{-5}j+(0.500*10^{-6} )i+(6.00*10^{-7}(-9.8m/s^{2} ))}{6.00*10^{-7}}\\a=[10.2j+0.833i]m/s^{2}](/tpl/images/0520/1028/7a95d.png)
