Answer:
i think Marco should replace ''ever again'' with ''very often''
Explanation:
''potato chips'' wouldn't really change the sentence, ''this week'' would only lower a few calories but he want to <u>improve</u> his body, and never eating junk food again is probably impossible so the only option left is: ''very often''
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>
I believe the answer is D
