Answer:

B. Cinética, debido a que esta energía está asociada con la velocidad que posee el tren.

Explanation:

Un tren de alta velocidad (TAV) o tren bala es aquel que alcanza velocidades iguales o superiores a 200 km/h. La energía que tiene el tren en su recorrido habitual es

A. Cinética, debido a que existen trenes elevados los cuales poseen altura y la altura está asociada con la energía cinética.

B. Cinética, debido a que esta energía está asociada con la velocidad que posee el tren.

C. Rápida, porque la energía cinética es sinónimo de rápido.

D. Potencial, debido a la potencia que tiene el tren para moverse.

Solution:

La energía cinética es la energía contenida en un objeto en movimiento. La energía cinética se puede definir como la cantidad de energía necesaria para que un objeto se acelere desde el reposo hasta su velocidad final.

La energía cinética (KE) viene dada por:

KE = (1/2) * masa * velocidad²

Podemos ver que la energía cinética depende de la masa del objeto y la velocidad del objeto.

El tren de alta velocidad posee energía cinética debido a la velocidad del tren.

A girl delivering newspapers covers her route by traveling 5.00 blocks west, 5.00 blocks north, and then 7.00 blocks east. What
FromTheMoon [43]

Answer:

P = 2i + 5j

Therefore she is 2 blocks east and 5 blocks north.

Resultant P = √(2^2 + 5^2) = √(4+25) = √29 = 5.4 blocks

Angle = taninverse (5/2)

Angle = 68.2°

Explanation:

Given:

Let west be negative and east be positive x axis.

Let north be the positive y axis.

5.00blocks west = -5.00 i

5.00 blocks north = 5.00 j

7.00 blocks east = 7.00i

Addition of the vector form of hee position is;

P = -5i +7i -5j

P = 2i + 5j

Therefore she is 2 blocks east and 5 blocks north.

Resultant P = √(2^2 + 5^2) = √(4+25) = √29 = 5.4 blocks

Angle = taninverse (5/2)

Angle = 68.2°

With what minimum speed must you toss a 200 g ball straight up to just touch the 12-m-high roof of the gymnasium if you release
masha68 [24]

Answer:

v = 14.41 m/s

Explanation:

It is given that,

mass of the ball, m = 200 g = 0.2 kg

Height of the roof, h = 12 m

The ball is tossed 1.4 m above the ground, h' = 1.4 m

Let v is the minimum speed with which the ball is tossed. Using the conservation of energy to find it as :

E_p=E_k

mg(h-h')=\dfrac{1}{2}mv^2

g(h-h')=\dfrac{1}{2}v^2

v=\sqrt{2g(h-h')}

v=\sqrt{2\times 9.8(12-1.4)}

v = 14.41 m/s

So, the minimum speed with which the ball is thrown straight up is 14.41 m/s. Hence, this is the required solution.
