Filiberto va a 90m/s en su carri, de repente se distrae por un par de segundos y su velocdad pasa a 40 m/s ¿cual fue su acelerac

svet-max [94.6K]

Answer:

Filiberto experimenta una deceleración de $2\,\frac{m}{s^{2}}$ .

Explanation:

(The problem was written in Spanish. Hence, explanation will be held in Spanish).

Asúmase que Filiberto se distrae por 2 segundos, puesto que un par equivale a dos, y que el vehículo experimenta un aceleración constante. La deceleración experimentada por el vehículo se deriva de la siguiente fórmula:

$a = \frac{v-v_{o}}{\Delta t}$

$a = \frac{40\,\frac{m}{s}-90\,\frac{m}{s} }{2\,s}$

$a = -25\,\frac{m}{s^{2}}$

Filiberto experimenta una deceleración de $2\,\frac{m}{s^{2}}$ .

1. If the angle of the ramp were increased from 30˙ to 45˙, how would this change the weight of the box? Explain.

yawa3891 [41]

When the angle of the ramp increases, the weight of the box acting perpendicular to the ramp decreases.

<h3>Normal reaction of the box</h3>

The normal reaction of the box is due to weight of the box acting perpendicular to the ramp.

Fn = Wcosθ

<h3>when the angle of the ramp = 30⁰</h3>

Fn = Wcos(30)

Fn = 0.866W

<h3>when the angle of the ramp = 45⁰</h3>

Fn = W x cos(45)

Fn = 0.7071W

Thus, when the angle of the ramp increases, the weight of the box acting perpendicular to the ramp decreases.
