Answer:
<em>la velocidad del auto es 15.75 m/s</em>
Explanation:
Potencia entregada a las ruedas P = 60 kW = 60000 W
masa del automóvil m = 1500 kg
ángulo de inclinación ∅ = 15°
velocidad del automóvil V =?
peso del automóvil W = mg
g = aceleración debido a la gravedad = 9.81 m/s^s
peso W = 1500 x 9.81 = 14715 N
Para acelerar el plano de inclinación, usamos la fórmula
potencia = (peso del automóvil W) x (velocidad del automóvil V) x sin∅
60000 = 14715 x V x sin 15°
60000 = 3808.52V
velocidad V = 60000 ÷ 3808.52 = <em>15.75 m/s</em>
Answer:
the statement that best describes the role of artificial heart is : The artificial heart has limited usefulness but can prolong life or be a tool to use while waiting for a transplant.
Explanation:
Although there are less chances of rejection while using the artificial heart but there is always a risk that artificial heart will not work properly and have to be ultimately replaced.
Studies have shown that artificial heart surgeries can lead to serious complications.
Also, artificial hearts do not work as healthy as natural ones.
