Given what we know, the type of motion that best describes the trajectory of the athlete and chair along the track is linear motion.
<h3>What is linear motion?</h3>
Linear motion is a type of motion that describes the movement of objects in a straight line. Depending on the exact design of the track this can be subcategorized as rectilinear motion or curvilinear motion. The latter being the case if the track contains a curve.
Therefore, given the motion produced by the athlete and the wheelchair, we can describe it as linear motion, and subcategorize it depending on the exact description of the track.

Answer:
3494444444.44444 J
-87077491.39453 J
Explanation:
M = Mass of Earth =
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
R = Radius of Earth =
h = Altitude =
m = Mass of satellite = 629 kg
v = Velocity of spacecraft =
The kinetic energy is given by
The spacecraft's kinetic energy relative to the earth is 3494444444.44444 J
Potential energy is given by
The potential energy of the earth-spacecraft system is -87077491.39453 J
Answer:
The correct option is B
Explanation:
The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion. A common physics demonstration relies on this principle that the more massive the object, the more that object resist changes in its state of motion.
Answer:
Explanation:
1) Olá, vamos calcular primeiramente o Volume da Piscina. Ela é uma piscina com uma forma tradicional, retangular. Temos a largura, o comprimento e a profundidade.
2) Precisamos fazer uma correlação entre a medida de capacidade (litro) e de volume, já que o custo é por litro d'água.
3) Observe que Francisco gasta 0,005 g de por semana.
Considerando que o mês tenha 4,5 semanas. E que quanto mais se trata a piscina mais se gasta Hipoclorito de Sódio. Temos uma relação diretamente proporcional.
Finalmente,
3.1) Rendimento do hipoclorito de produto em gramas por semana:
3.2) Consumo mensal (y), considerando 4,5 semanas:
3.3) O custo da manutenção, já que 18 kg de custa R$ 135 e são grandezas diretamente proporcionais:
