A girl pulls on a 10-kg wagon with a constant horizontal force of 30 N. If there are no other horizontal forces, what is the wagon's acceleration in meters per second per second?
A) 10
B) 0.3
C) 30
D) 3.0
E) 300

Quizplus · Accepted Answer

The acceleration can be calculated using Newton's second law, $F = ma$, where $F$ is the force applied, $m$ is the mass of the object, and $a$ is the acceleration. Substituting the given values, $30 \, \text{N} = 10 \, \text{kg} \cdot a$, solving for $a$ gives $a = 3.0 \, \text{m/s}^2$.
