in the formula f = m . a, if f is 20 newtons and m is 5 kg, then a is\nvelocity\n100 kg\n4 m/s²\n25 m/s²\n4 kg

Explanation:

Step1: Rearrange the formula

Given $F = m\cdot a$, we can solve for $a$ by dividing both sides by $m$, so $a=\frac{F}{m}$.

Step2: Substitute the given values

Substitute $F = 20$ N and $m = 5$ kg into the formula $a=\frac{F}{m}$. Then $a=\frac{20}{5}$.

Step3: Calculate the result

$\frac{20}{5}=4$ m/s².

Answer:

4 m/s²
