Question

always use significant figure rules. remember that these rules apply to all numbers that are measurements.
in working this problem, assume the value of \g\ to be 9.8 m/s² with two (2) significant digits unless otherwise stated.
a horse pulls on an object with a force of 300 newtons and does 12,000 joules of work. how far was the object moved?
______ m
○ 40
○ 10 × 10⁴
○ 5 × 10⁵
○ 0.03

Explanation:

Step1: Escribir la fórmula del trabajo

El trabajo \( W \) se define como \( W = F\times d \), donde \( F \) es la fuerza y \( d \) es la distancia.

Step2: Despejar la distancia \( d \)

Reordenando la fórmula: \( d=\frac{W}{F} \)

Step3: Sustituir los valores

Dado \( W = 12000\space J \) y \( F = 300\space N \), entonces \( d=\frac{12000}{300} \)

Step4: Calcular el valor de \( d \)

\( d = 40\space m \)

Answer:

40
