Problem 40PE
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.

ANSWER:
Solution 40PE
Step 1 of 8
Breeze blowing parallel to the ground, by exerting a force of on a flea with mass
, when the flea jumps with a force of
straight down the ground. Here we need to calculate the direction and magnitude of the flea by including the gravitational force.
We can calculate the net force using the free body diagram of the flea. Then by using the calculated net force, we can estimate the direction and magnitude of acceleration using Newton’s second law.
