Answer:

La cinemática es la parte de la física que estudia el movimiento, sin importar la causa que lo produce, es

decir, su objetivo es describir cómo se mueve un cuerpo. En esta materia introductoria, esta descripción será

independiente de la forma y tamaño de los cuerpos en movimiento. Hablaremos del movimiento de un

átomo, de una pelota o de un tren, sin embargo, a los fines prácticos siempre vamos a pensar al objeto en

cuestión como una partícula o cuerpo puntual.

Decimos que una partícula se mueve si la vemos cambiar de lugar, es decir que ocupa distintas posiciones

en distintos instantes. Entonces, la idea de movimiento relaciona el espacio y el tiempo.

Para poder encarar el tema, es necesario definir algunos conceptos que permitan “medir” las características

del movimiento de un cuerpo. Estos conceptos en física se denominan magnitudes y pueden ser vectoriales o

escalares.

La posición, el desplazamiento, la velocidad y la aceleración son magnitudes vectoriales. El tiempo y el

lapso son magnitudes escalares. Asimismo, definiremos otros conceptos como: distancia, trayectoria y

sistemas de referencia.

Veremos que describir el movimiento de un cuerpo/objeto implicará conocer su posición, velocidad y

aceleración en función del tiempo. Para lograr esa descripción será necesario definir un sistema de referencia

para la posición y otro para el tiempo.

What is the magnitude of the velocity when the elastic potential energy is equal to the kinetic energy? (Assume that U=0 at equi
zhannawk [14.2K]

Answer:

Explanation:

General Equation of SHM is given by

x=A\cos \omega t

v=-A\omega \sin \omega t

where x=position of particle

A=maximum Amplitude

\omega =angular frequency

t=time

At any time Total Energy is the sum of kinetic Energy and Elastic potential Energy i.e. \frac{1}{2}kA^2

where k=spring constant

Potential Energy is given by U=\frac{1}{2}kx^2

also it is given that Potential Energy(U) is equal to Kinetic Energy(K)

Total Energy=K+U

Total=2U=2\times \frac{1}{2}kx^2

\frac{1}{2}kA^2=2\times \frac{1}{2}kx^2

x=\pm \frac{A}{\sqrt{2}}

at x=\frac{A}{\sqrt{2}}

velocity is v=\frac{A\omega}{\sqrt{2}}

With an initial velocity of 20km per hour a car accelerated at 8m/s2 for 10s,what is the position of the car at the end of 10s
Dima020 [189]
  • initial velocity=u=20km/h=5.5m/s
  • Acceleration=a=8m/s^2
  • Time=t=10s

\\ \sf\longmapsto s=ut+\dfrac{1}{2}at^2

\\ \sf\longmapsto s=5.5(10)+\dfrac{1}{2}(8)(5.5)^2

\\ \sf\longmapsto s=55+4(5.5)^2

\\ \sf\longmapsto s=55+4(30.25)

\\ \sf\longmapsto s=55+121

\\ \sf\longmapsto s=176m

Which law of motion accounts for the following statement?

I know that its not the second law. I'm almost positive its the first one. Please let me know if I'm wrong. This sentence makes no sense when you put it with the third law. So, the first law is my guess...
