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>
