What force is necessary to accelerate a 50kg box at 30 m/s2?

Definición como rama de la física y su campo de estudio.

taurus [48]

Answer:

Ver la explicacion abajo.

Explanation:

La física es una ciencia exacta que explica las propiedades de la materia y de la energía, por medio de leyes y ecuaciones explica los fenómenos naturales que suceden a nivel microscópico y macroscópico. La física se puede dividir en estudios de la mecánica clásica y de la mecánica cuántica.

Mecanica clasica

Se ocupa de los fenomenos fisicos que suceden a nivel macroscopico, donde se pueden aplicar las leyes de Newton para explicar los diferentes fenomenos que suceden a nivel universal. Esto sucede a velocidades mucho menores comparadas a la velocidad de la luz.

Mecanica cuantica.

Estudia sistemas de pequeña escala, como atomos y particulas elementales.

Mecanica Relativista

Describe comportamiento de cuerpos que se mueven con velocidades cercanas a la velocidad de la luz. A partir de ahi no se pueden utilizar las mismas ecuaciones de la mecanica clasica para describir los comportamientos fisicos de los cuerpos.

how does a sprinter sprint what is the forward force on a sprinter as she accelerates. where does that force come from

NARA [144]

On the starting blocks, sprinters use their feet to push backward. The blocks respond by pressing forward with a force equal to this with their feet.

<h3>What drives the sprinter forward?</h3>

Vertical forces must be larger than the pull of gravity in order to assist the sprinter in moving forward as gravity is pushing him or her downward. The propulsive force is the force that propelled the runner forward.

<h3>Basketball players must jump straight up into the air, but how?</h3>

An interaction diagram and a free-body diagram should be included in your explanation. The player pushes down on the ground, which pushes up against him in return. As a result of his push being stronger than gravity, the player accelerates upward.

How does the force of gravity affects an objects acceleration

MrRissso [65]

Answer:

When objects fall to the ground, gravity causes them to accelerate.

Explanation:

Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls.

Neon is compressed from 100 kPa and 24°C to 500 kPa in an isothermal compressor. Determine the change in the specific volume and

trasher [3.6K]

Answer:

ΔV = -0.97 m³/ kg

ΔH = 0 kJ/ kg

Explanation:

To determine the change in the specific volume we need to use the ideal gas law:

$PV = RT$

where P: pressure of the gas V: volume of the gas, R: ideal gas constant= 0.4119 kJ/kg.K = 0.4119 kPa.m³/kg.K and T: temperature of the gas.

The V₁, at a compressed pressure is:

$V_{1}= \frac {RT}{P_{1}}$
