Why can work be thought of as the transfer of energy? Please help it's physics
deff fn [24]
That is because work requires energy. According to the law of conservation of energy, it cannot be created or destroyed. When doing work, energy change forms and gets transferred to the object until it is released.
for example, when you lift up an object and place it on a higher elevation, you transferred energy to it and gave it potential energy. The potential energy is transformed into kinetic energy when the object falls down, and if it hits a surface, the energy will scatter, vibrating the areas around it and producing sound.
Also, work= force X distance. The energy does not go away, but rather get changed into some other form of energy

En un parque de atracciones hay una montaña rusa donde los primeros 140 metros son en línea recta, si desde que el carrito esta
zubka84 [21]

Answer:

Tiempo, t = 6.11 segundos.

Explanation:

Dados los siguientes datos;

Distancia = 140 m

Aceleración = 7,5 m/s²

Dado que el objeto partió del reposo, su velocidad inicial es igual a 0 m/s.

Para encontrar el tiempo, usaríamos la segunda ecuación de movimiento;

S = ut + ½at²

Dónde;

S representa el desplazamiento o la altura medida en metros.

u representa la velocidad inicial medida en metros por segundo.

t representa el tiempo medido en segundos.

a representa la aceleración medida en metros por segundo cuadrado.

Sustituyendo en la ecuación, tenemos;

140 = 0*t + ½*7.5*t²

140 = 0 + 3.75t²

140 = 3.75t²

Dividiendo ambos lados por 3,75, tenemos;

t² = 140/3.75

t = √37.33

Tiempo, t = 6.11 segundos
