Try this first
If a 5 kg object is subjected to a force of 20 N, what is its acceleration?.
- A.4 m/s²
- B.5 m/s²
- C.2 m/s²
- D.10 m/s²
Model answer
What a good answer should say
- 4 m/s²
Explanation
Why this works
Using F = ma, rearranging gives a = F/m. Substituting the values: a = 20 N / 5 kg = 4 m/s².
Thus, the acceleration of the object is 4 m/s².
