Which of the following best describes newton's second law of motion? (more than one answer applies)

f=m • a

a swimmer turns and kicks off from the end of the pool.

a book will slide across the desk if you exert a force on it.

an object in motion will remain in motion in the same direction and at a constant speed unless another force acts on it.

law of inertia

shows the relationship between mass, force and acceleration.

for every action there is an equal and opposite reaction.

when a hammer strikes a nail, the nail exerts a force back on the hammer.

F=m • a

A swimmer turns and kicks off from the end of the pool.

A book will slide across the desk if you exert a force on it.

Explanation:

The first one, F = ma is a direct expression of the Newton's second law of motion. This is because the force exerted on an object changes its momentum like this:

where (acceleration is change in velocity with respect to time)

Thus, the equation will be in the form:

F = ma

The second scenario points to an acceleration produced as a result of the force on an object. This time the feet propel the motion hence,

The third scenario is the fact that the force produces acceleration on the book.

the answer is a for sure mark brainliest i had got this right on usatestprep
