How does the gravity in the space shuttle compare with the gravity on earth’s surface?

These days they are exactly identical. All the space shuttles are currently in museums located on the surface of the Earth.

Years ago when the space shuttles were in orbit, the gravity inside a shuttle was about 85% of the gravity on the Earth's surface.

The gravity in the space shuttle is approximately equal to the gravity on the surface of the earth

A leaky 10-kg bucket is lifted from the ground to a height of 16 m at a constant speed with a rope that weighs 0.7 kg/m. initial

IrinaVladis [17]

$\displaystyle W =\lim_{n\to\infty}{\sum_{i=0}^{n}{(678.16 - 36.26\;x_i)\cdot\dfrac{16}{n}}}$ .

<h3>Explanation</h3>

The mass comes in three parts:

the mass of the rope,
the mass of the water in the leaky bucket, and
the mass of the bucket.

Both the mass of the rope $m_\text{rope}$ and the mass of the water in the bucket $m_\text{water}$ varies with the height $x$ of the bucket. Express the two masses as a function of $x$ :

$m_\text{rope} = 0.7\;(16 - x)$ ,

The water in the bucket behaves like yet another rope of density $48 \;\text{kg}/ 16 \;\text{m}= 3.0\;\text{kg}\cdot\text{m}^{-1}$ . The mass of the water left in the bucket at height $x$ will be

$m_\text{water} = 3.0\;(16 - x)$ .

The mass of the bucket is $10\;\text{kg}$ . Combining the three:

$m(x) = m_\text{rope}(x) + m_\text{water}(x) + m_\text{bucket} \\\phantom{m(x)} = 0.7\;(16-x) + 3.0\;(16 - x) + 10\\\phantom{m(x)} = 69.2 - 3.7\;x$ .

Weight of the bucket at height $x$ :

$F_\text{weight}(x) = m(x)\cdot g = 9.8\;(69.2 - 3.7\;x) = 678.16 - 36.26\;x$ .

The bucket moves upward at a constant speed. As a result,

$F(x) = W(x) = 678.16 - 36.26\;x$ .

Express the work required as a definite integral:

$\displaystyle W = \int_{0}^{16}{F(x) \cdot dx} = \int_{0}^{16}{(678.16 - 36.26\;x)\cdot dx}$ .

Rewrite the definite integral as a Riemann Sum:

$\displaystyle W = \int_{0}^{16}{(678.16 - 36.26\;x)\cdot dx} \\\phantom{W}= \lim_{n\to\infty}{\sum_{i=0}^{n}{(678.16 - 36.26\;x_i)\cdot\frac{16-0}{n}}}\\\phantom{W} = \lim_{n\to\infty}{\sum_{i=0}^{n}{(678.16 - 36.26\;x_i)\cdot\frac{16}{n}}}$ .

A ___ force is not path-dependent and does not change the overall mechanical energy of an object.

finlep [7]

Answer:

conservative

Explanation:

Nonconservative force is the force that depends on a path, however conservative does not depend on a path and it is not associated with the potential energy. When the work is done by an unconservative force, mechanical energy is added or removed. Friction is the best example for a non-conservative force. When these non-conservative forces are acting, the mechanical energy changes but these are not preserved.

Why do objects keep moving after the force stops acting on it

saul85 [17]

It keeps moving for just a few seconds because of inertia. Say you are going 50 miles down the interstate there is a stop sign when you stop you almost come out of your set that is why we have to wear set belts and that is an example of Inertia. Glad to help
