Question

A horse track is a loop where the starting point and the finish line are at the same point. A horse gallops
around a 400 m track in 20 s. Calculate the velocity of the horse.
answers:

0.05 m/s

20 m/s

0 m/s

40 m/s

Answer 1

To calculate the velocity of the horse, we need to consider the definition of velocity as the displacement divided by the time taken. In the case of the horse galloping around the track, the displacement is zero because the horse starts and ends at the same point (the finish line is in the same location as the starting point).

Given:

- Displacement = 0 m (since it returns to the starting point)
- Time = 20 s

Using the formula for velocity:

\[
\text{Velocity} = \frac{\text{Displacement}}{\text{Time}} = \frac{0 \text{ m}}{20 \text{ s}} = 0 \text{ m/s}
\]

Therefore, the velocity of the horse is 0 m/s.

The correct answer is:

**0 m/s**
