A flea jumps by exerting a force of 1.20 ×10^-5 N straight...

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

Key Concepts

Force Decomposition

Force decomposition involves breaking down a force into its perpendicular components, typically using coordinate axes (such as horizontal and vertical). This technique is essential when dealing with forces acting in different directions, as it simplifies the process of vector addition and helps in determining the net force and the subsequent acceleration along each axis.

Gravitational Force

Gravitational force, often referred to as weight, acts on a mass due to the gravitational pull of the Earth. It is calculated by multiplying the mass of the object by the acceleration due to gravity (mg). This force always acts in the downward direction and is crucial when calculating the net force on an object that is also subject to other forces.

Newton's Second Law

Newton's Second Law states that the net force acting on an object is equal to the product of its mass and acceleration (F = ma). This principle allows us to calculate the acceleration of an object when multiple forces are acting on it by summing these forces to determine the overall net force and then dividing by the object's mass.

Vector Addition

Vector addition is the method of combining two or more forces that act in different directions. Since force is a vector, both magnitude and direction must be considered. By adding the individual force vectors appropriately, one can find the resultant, or net, force which determines the object's acceleration.
