Question

sam exerts a force (f) of 65 n on a lawn mower with a mass (m) of 25 kg. which formula can be used to calculate the acceleration (a) of the lawn mower?
(a = f\times m)
(a = fdiv m)
(a = f + m)
(a = f - m)

Explanation:

Step1: Recall Newton's second - law

Newton's second - law is $F = ma$, where $F$ is force, $m$ is mass and $a$ is acceleration.

Step2: Solve for acceleration

We need to isolate $a$ in the formula $F = ma$. Divide both sides of the equation by $m$: $a=\frac{F}{m}$.

Answer:

None of the given options are correct. The correct formula is $a = \frac{F}{m}$.
