Answer :
Final answer:
The net horizontal force applied on the pedals is 235 N, and the total mass of the boy and bike is 48 kg. Therefore, the acceleration of the boy and bike is 4.896 m/s².
Explanation:
To calculate the acceleration of the boy and the bike, we need to use Newton's second law, which states that force equals mass times acceleration (F = ma).
We know that the net horizontal force applied by the pedals is 235 N and the total mass of the boy and the bike is 48 kg.
So, to find the acceleration, we can rearrange the formula:
a = F/m = 235 N / 48 kg = 4.896 m/s².
