Question

qse 1 retest 25-26
which scenario best describes how to increase the acceleration of a cart being pushed by a student?
the acceleration cant be changed.
the student pushes with more force.
the student pushes with less force.
the student adds more mass to the cart.

Explanation:

According to Newton's second - law $F = ma$ (where $F$ is force, $m$ is mass and $a$ is acceleration), acceleration $a=\frac{F}{m}$. To increase acceleration, either increase the force $F$ or decrease the mass $m$. Pushing with more force increases $F$, which will increase $a$.

Answer:

The student pushes with more force.
