Explanation:
The question can be solved by using Newton's second law:
F = ma
where
F is the net (unbalanced) force on the cyclist
m is the mass of the cyclist
a is his acceleration
In this problem:
m = 50 kg
Therefore, the unbalanced force is
That's a perfect example of a chemical change,
because a new substance is formed.
