Exam-style question
Try this first
A cyclist exerts a force of 200 N to accelerate their bike. If the mass of the bike and cyclist combined is 80 kg, what is the acceleration of the bike?.
Model answer
What a good answer should say
- The acceleration of the bike is 2.5 m/s².
Explanation
Why this works
This question assesses the ability to apply Newton's second law, F = ma, to find acceleration. By rearranging the formula and substituting the known values, the answer demonstrates a clear understanding of the relationship between force, mass, and acceleration.
