Una máquina de tiro al plato lanza los mismos con un ángulo de 45° respecto al suelo y a una velocidad inicial de 100 km/h. ¿Qué altura máxima alcanzarán los platos? ¿Cuál será su alcance máximo?

Explanation:

A target shooting machine launches them at an angle of 45 ° to the ground and at an initial speed of 100 km / h. What maximum height will the dishes reach? What will be its maximum range?

Given that,

Then initial speed is 100km/hr

U = 100km/hr

U = 100×1000 / 3600

U = 27.78 m/s

And the angle of projection is 45°

θ = 45°

A. Maximum height?

The maximum height is given as

H = U²•Sin²θ / 2g

g = 9.81m/s²

Then,

H = 27.78² Sin²45 / 2 × 9.81

H = 27.78² × Sin45 × Sin45 / 19.62

H = 19.66 m

B. Maximum range R?

The range can be calculated using

R = U² Sin2θ / g

Rmax = U² / g

We can have maximum range when θ = 45°, and since θ is given to be 45°, then, we can use maximum range formula

R = U² / g

R = 27.78²/9.81

R = 78.65 m

The maximum range is 78.65m

Spanish

Dado que,

Entonces la velocidad inicial es de 100 km / h

U = 100 km / h

U = 100 × 1000/3600

U = 27.78 m / s

Y el ángulo de proyección es de 45 °

θ = 45 °

A. Altura máxima?

La altura máxima se da como

H = U² • Sin²θ / 2g

g = 9.81m / s²

Entonces,

H = 27.78² Sin²45 / 2 × 9.81

H = 27.78² × Sin45 × Sin45 / 19.62

H = 19.66 m

B. Rango máximo R?

El rango se puede calcular usando

R = U² Sin2θ / g

Rmáx = U² / g

Podemos tener un rango máximo cuando θ = 45 °, y dado que θ es 45 °, entonces, podemos usar la fórmula de rango máximo

R = U² / g

R = 27.78² / 9.81

R = 78.65 m

El alcance máximo es de 78.65 m.

-first use of geothermal energy occurred more than 10,000 years ago in north america by american paleo-indians

-the first industrial use of geothermal energy began near pisa, italy in late 18th century

-in 1904, italian scientist piero ginori conti invented the first geothermal electric power plant in which steam was used to generate the power

-with the above experiment, the first geothermal plant in usa started in 1922 with a capacity of 250 kilowatts

-however, in 1946 first ground-source geothermal heat pump installed at commonwealth building in portland, oregon

-during the 1960’s, pacific gas and electric began operation of first large scale geothermal power plant in san francisco, producing 11 megawatts

-in 1973, when oil crisis began many countries began looking for renewable energy sources and by 1980’s geothermal heat pumps (ghp) started gaining popularity in order to reduce heating and cooling costs

-as effect of climate change started showing results, governments of various countries joined hands to fight against it, for which kyoto protocol was signed in japan in 1997, laid out emission targets for rich countries and required that they transfer funds and technology to developing countries, 184 countries have ratified it

hope this
