Question

in the formula ( f = m cdot a ), if ( f ) is 20 newtons and ( m ) is 5 kg, then ( a ) is (\bigcirc) velocity (\bigcirc) 100 kg (\bigcirc) 4 m/s² (\bigcirc) 25 m/s² (\bigcirc) 4 kg

Explanation:

Step1: Recall the formula \( F = m \cdot a \)

We need to find \( a \), so we can rearrange the formula to \( a=\frac{F}{m} \).

Step2: Substitute the given values

Given \( F = 20 \) Newtons and \( m = 5 \) Kg. Substitute into the formula: \( a=\frac{20}{5} \).

Step3: Calculate the result

\( \frac{20}{5}=4 \), so \( a = 4 \, \text{m/s}^2 \).

Answer:

4 m/s² (corresponding to the option "4 m/s²")
