Question

A horse walks along a straight path. it travels 3 in one second, 4 m in the next second, and 5 m in the third second. describe the horse's motion

Answer 1

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 $a$ is defined as the change of velocity in time we can calculate it:

$a\frac{4 m/s-3 m/s}{1 s}=1m/s^{2}$ This is the horse's constant acceleration
