4.7 Exercise 6

Avg difficulty 2.5

A flea jumps by exerting a force of 1.20×10−5 N1 . \text{20} \times \text{10}^{- 5} \text{ N} straight down on the ground. A breeze blowing on the flea parallel to the ground exerts a force of 0.500×10−6 N0 . \text{500} \times \text{10}^{- 6} \text{ N} on the flea. Find the direction and magnitude of the acceleration of the flea if its mass is 6.00×10−7 kg6 . \text{00} \times \text{10}^{- 7} \text{ kg}. Do not neglect the gravitational force.
