A book falling to the floor is best described by: law one, law two, law three, or all three laws?
Law Incorporation [45]

The book falling to the floor is described by Newton's second law and Newton's third law

Explanation:

Newton's first law of motion states that:

"An object moving at constant velocity (or at rest) keeps moving at constant velocity (or will stay at rest) unless acted upon unbalanced, external forces"

For a book falling to the floor, there is an unbalanced force acting on it (the  force of gravity): therefore, we cannot apply Newton's first law.

Newton's second law of motion states that:

"The net force acting on an object is equal to the product between the object's mass, m, and its acceleration, a"

Mathematically:

F=ma

For the book falling to the floor, F is the force of gravity; therefore, we can apply Newton's second law, and in this case it tells us that the book has a non-zero acceleration during its fall.

In particular, the force of gravity is F=mg (where g is the acceleration due to gravity), so the acceleration of the book is

mg=ma\\a=g=9.8 m/s^2

Newton's third law of motion states that:

"When an object A exerts a force (action force) on an object B, then object B exerts an equal and opposite  force (reaction force) on object A".

In this case, the Earth is exerting a  force (the force of gravity) on the book during its fall: therefore, the book is also exerting a equal and opposite force (reaction force) on the Earth.

Physics question!!!
lesantik [10]

Answer:

4.5 metres

Explanation:

Using Hooke's Law (F\propto x)

We need to find the spring constant of the bungee cord with the given extension and force, we can do this by substituting in known values.

600=3k\\k=200

Now we have found the spring constant of the bungee cord, we can substitute it in for the a different force. As the cord is the same we can use the same spring constant.

900=200x\\x=4.5

A particle moves so that its position as a function of time in SI units is r = i + (3.0) t2 j + t k. Write expressions for its v
maksim [4K]

Answer:

i - component of V is zero for any value of t  i-e  no motion in this direction

Explanation:

Since

r= i+3t^{2}j+t k

==> V = \frac{d r}{dt}=\frac{d(i+3t^{2}j+kt) }{dt}

=6tj+k

and acceleration is given by taking derivative of velocity w.r.t  t

==> a= \frac{dV}{dt}=\frac{d(6tj+k)}{dt}=6j

so, V=0i+6tj+k

and

a = 0i+6j+k

i - component of V is zero for any value of t  i-e  no motion in this direction
