7 0

Answer:

v_{f} = - M / m v

Explanation:

We must define a system formed by the wagon and the torro, in this case the forces of the movement are internal, so the moment is preserved, write the moment in two moments

Initial. Before the bull's movement, in this case the two are still

             p₀ = 0

Final. The bull is moving

            p_{f}= M v + m v_{f}

             p₀ = p_{f}

              0 = M v + mv_{f}

We cleared the train speed

            v_{f} = - M / m v

The negative sign indicates that the train moves in the opposite direction of the bull

If the moon were twice as far from years as it is now the following would be true
zubka84 [21]
The question is incomplete.

The distance between the Moon and Earth influences: 1) the attractive gravitational force between them, 2) the tides, 3) the eclipses, 4) the period of each full turn of the moon around the Earth.

Assuming the question refers to the gravitational attraction, we must use the fact that, as per, Newton's Universal Gravitaional Law, the attractive force between the two bodies is inversely related to the square distance that separates them.

Then, if the Moon were twice as far, the gravitational pull would be one fourth (1/4) of actual pull.

How is velocity ratio of wheel and axle calculatedaad<br>​
iogann1982 [59]

Answer:

VR = \frac{Radius of wheel}{Radius of axle}

Explanation:

A machine is a device that can be used to overcome a load by the application of an effort through a pivot. Examples are: pulleys, wedge, screw jack, wheel and axle etc.

The wheel and axle is a simple device that can be used to lift a load through a height. Its velocity ratio (VR) can be determined by:

VR = \frac{Radius of wheel}{Radius of axle}

Note that for a practical wheel and axle, the radius of the wheel is greater than the radius of the axle.
