Question

a force of 30 n is applied for 5.0 s on two objects with different masses. which one has the greater acceleration? multiple choice both objects experience the same change in momentum. the object with the smaller mass. the object with the larger mass. it depends on the direction of the applied force.

Explanation:

1. Recall Newton's second law: $F = ma$, so $a=\frac{F}{m}$.
2. Force $F$ is the same (30 N) for both objects. Acceleration $a$ is inversely proportional to mass $m$. Smaller mass means larger acceleration.
3. For momentum change, $\Delta p = F\Delta t$. Since $F$ and $\Delta t$ (5.0 s) are same, $\Delta p$ is same, but the question asks about acceleration, so the key is $a$ vs $m$ relation.

Answer:

The object with the smaller mass.
