Question

1. determine the amount of force needed for mark to have pushed his suv with a mass of 2,460 kg to the nearest gas station at 0.05 m/s².

a. 271 newtons
b. 68 newtons
c. 80 newtons
d. 123 newtons

1. which of the following best represents the relationships among the net force on marks suv, its mass, and its acceleration as it sits still on the side of the highway.
2. which of the following statements is true of marks suv when it was slowing down?

a. a forward force must be decreasing at the same amount as the frictional force.
b. the forward force moving the object forward must be increasing.
c. the frictional force causing the object to slow down must be decreasing.
d. the frictional force that is causing the object to slow must be greater than the sum of the acceleration forces that are pulling or pushing the object forward.

Explanation:

Step1: Aplicar la segunda ley de Newton

La segunda ley de Newton establece que \( F = ma \), donde \( F \) es la fuerza neta, \( m \) es la masa y \( a \) es la aceleración.

Step2: Sustituir los valores dados

Dado que \( m = 2460\ \text{kg} \) y \( a = 0.05\ \text{m/s}^2 \), sustituimos en la fórmula: \( F=(2460\ \text{kg})(0.05\ \text{m/s}^2) \).

Step3: Realizar el cálculo

\( F = 2460\times0.05=123\ \text{N} \).

Answer:

D. 123 Newtons
