Necesito ayuda urgente por favor, gracias 2) Sabiendo que el espacio que recorre un cuerpo en función del tiempo viene dado por la siguiente ecuación: X(t)=t 2 -8t+6, donde x se mide en metros y t en segundos. a) Realizar la gráfica , posición-tiempo de en el intervalo [0,5] Nota: Tabular para t=0,1,2,3,4,5, ubicar los puntos sobre el plano y luego unir los puntos con una curva. b) Que distancia habrá recorrido en un minuto.

Clothing made of several thin layers of fabric with trapped air in between, often called ski clothing, is commonly used in cold climates because it is light, fashionable, and a very effective thermal insulator. so it is no surprise that such clothing has largely replaced thickand heavy old-fashioned coats. (a) consider a jacket made of five layers of 0.1-mm-thick synthetic fabric (k = 0.13 w/m·°c) with 1.5-mm-thick air space (k = 0.026 w/m·°c) between the layers. assuming the inner surface temperature of the jacket to be 28°c and the surface area to be 1.25 m2, determine the rate of heat loss through the jacket when the temperature of the outdoors is 0°c and the heat transfer coefficient at the outer surface is 25 w/m2·°c. (b) what would your response be if the jacket is made of a single layer of 0.5-mm-thick synthetic fabric? what should be the thickness of a wool fabric (k = 0.035 w/m·°c) if the person is to achieve the same level of thermal comfort wearing a thick wool coat instead of a five-layer ski jacket?
