The acceleration of a moving vehicles is 10 metre per second square what does it means

pochemuha

Answer:

Acceleration is the rate of change of velocity. What is commonly said as ‘ten meter per second squared’ can bee broken down into ‘ten meter per second per second.’ This gives us the true meaning of the term acceleration.

Just like ‘ten meter per second’ means increasing the displacement by ten meters every second, ‘ten meter per second per second’ means increasing the velocity by ten meters per second every second.

So, basically if you consider the case of a free fall motion, where ‘t’ stands for time and ‘v’ stand for velocity at that instant:

At,

t=0, v=0 m/s

t=1, v=0+10 m/s;

t=2, v=0+10+10 m/s;

t=3, v=0+10+10+10 m/s;

This can also be thought as a Arithmetic Progression where common difference ‘D’ is the acceleration(a), since it adds a 10 m/s to velocity every second and the first term ‘A’ stands for the initial velocity (u). Using this approach we can derive to the first equation of motion:

v = u + at

1The specific heat of substance (X) is greater than that for substance (Y). If equal amounts of heat are added to both these sub

geniusboy [140]

Answer:

Substance Y

Explanation:

A substance with a high specific heat capacity can absorb a large quantity of heat before it will raise in temperature. A substance with a low specific heat requires relatively little heat to raise its temperature. Thus, if the same amount of energy was added to both substances, substance Y will reach the higher temperature, while substance X would require more energy to reach high temperatures.

A stone is thrown vertically upward with an initial speed of 24.7 m/s. Neglect air resistance. The speed of the stone when it is

fredd [130]

Answer:

The speed of the stone when it is 4.66 m higher is 236.057 m/s.

Explanation:

Given the initial velocity and vertical distance, we can use the fourth kinematic equation ( $v^{2} =v_{o}^{2}+2ay$ ) to find v final, or the v to the left of the equal sign. We know $v_{o}$ (initial velocity) is 24.7 m/s, y (change in vertical distance) is 4.66 m, and a is another way to write g (acceleration due to gravity), or 9.8 $m/s^{2}$ .

From here you could plug in the values and solve for v final, but to make the solving process simpler, we can simplify the given equation, <em>then </em>plug in the known values.

To isolate v final, we can take the square root of $v^{2}$ and do the same to the right side of the equation. Therefore, we can find v final with: $v_{o} \sqrt{2ay}$ , where v initial is outside of the square root because it squared...

If we plug in the known values to the simplified equation, we get: $v=24.7m/s*\sqrt{2(9.8m/s)(4.66 m)}$

The final answer is 236.057 m/s.

A crane raises a crate with a mass of 150 kg to a height of 20 m. Given that

Virty [35]

Answer:

$\boxed {\boxed {\sf 29,400 \ Joules}}$

Explanation:

Gravitational potential energy is the energy an object possesses due to its position. It is the product of mass, height, and acceleration due to gravity.

$E_P= m \times g \times h$

The object has a mass of 150 kilograms and is raised to a height of 20 meters. Since this is on Earth, the acceleration due to gravity is 9.8 meters per square second.
