Wants to slide his 430g water bottle precisely 12m to land inside a Bull's Eye! If the coefficient of kinetic friction between t
AleksAgata [21]

Answer:

Ff = u M g    frictional force where u = .62

1/2 M v^2    kinetic energy of water bottle at release

Ff * d = 1/2 M v^2 = u M g d   work to stop equals initial kinetic energy

v^2 = 2 u g d = 2 * .62 * 9.8 * 12 = 146 m^2 / s^2

v = 12.1 m/s

At one instant of time a rocket is traveling in outer space at 2500m/s and is exhausting fuel at a rate of 100 kg/s. If the spee
lawyer [7]

Thrust is a reaction force described quantitatively by Newton's third law. When a system expels or accelerates mass in one direction, the accelerated mass will cause a force of equal magnitude but opposite direction on that system. Mathematically can be written as,

T = v\frac{dm}{dt}

Here,

v = speed of the exhaust gases measured relative to the rocket.

\frac{dm}{dt}= Rate of change of mass with respect to time

Our values are given as,

v = 1500m/s

\frac{dm}{dt} = 100kg/s

Replacing we have that

T = 1500*100

\therefore T = 1.5*10^5N

In 1600, Dr. William Gilbert coined the term “electrica,” a word that gave rise to our word electricity.
mrs_skeptik [129]

They recorded the first references to electrical effects, such as static electricity and lightning, over 2,500 years ago. It was not until 1600 that a man named Dr. William Gilbert coined the term “electrica,” a Latin word which describes the static charge that develops when certain materials are rubbed against amber.

PLEASE HELP. GRAVITY QUESTION, WRITTEN RESPONSE.
Rina8888 [55]

1) Forces acting on your body: force of gravity and normal reaction

2) Due to Newton's second law, N = mg

Explanation:

1)

When you sit on the computer, there are only two forces acting on you:

  • The force of gravity, acting downward, of magnitude W=mg, where m is your mass and g=9.8 m/s^2 is the acceleration due to gravity, downward
  • The normal reaction exerted by the chair on you, N, acting upward

Your body is in equilibrium (it doesn't move), this means that the two forces balance each other, therefore:

N-mg=0\\N=mg

2)

We can now apply Newton's second law of motion to this situation; this law states that the net force acting on a body is equal to the product between its mass and its acceleration. Mathematically,

\sum F = ma

where

\sum F is the net force

m is the mass

a is the acceleration

In this situation, the net force is

\sum F = N-mg

So the equation becomes

N-mg=ma

However, we observe that your body is at rest; therefore, the acceleration is zero:

a = 0

And therefore,

N-mg=0\\N=mg

Is gravitational pull strengthened by distance?
topjm [15]

I'm not sure but I think that if objects are closer (less distant), than the gravitational pull is stronger. I'm sorry if I couldn't really help I remember learning about this kind of.
