Answer: The horse is moving with a uniform acceleration
Explanation:
According to the described situation, we are dealing with a constant acceleration (also called uniform acceleration), since the horse's velocity is changingn by a constant rate.
Let's prove it:
Firstly we are told the horse follows a straight path. In addition we are given its velocity:
3 m/s, then 4 m/s and 5 m/s
Since acceleration [tex]a[/tex] is defined as the change of velocity in time we can calculate it:
[tex]a\frac{4 m/s-3 m/s}{1 s}=1m/s^{2}[/tex] This is the horse's constant acceleration
