Suzanne spends 2 hours riding her horse from Deer Creek Dam to the campground. The trail is around 4000 meters long. When Suzanne reaches the campground, the horse is galloping at a speed of 8 meters per second.

What is the average acceleration of her horse?

Answer :

Final answer:

The average acceleration of Suzanne's horse, assuming it started from rest, is approximately 0.0011 m/s². This is calculated by subtracting the initial velocity from the final velocity and dividing by the time taken, in this case 7200 seconds (2 hours converted into seconds).

Explanation:

In order to calculate the average acceleration of Suzanne's horse, it's important to understand that acceleration is the rate of change of velocity per unit of time. In this case, we know the final velocity (8 m/s), but the initial velocity isn't provided. If we assume that the horse started from rest (0 m/s), then the average acceleration would be calculated using the formula: acceleration = (final velocity - initial velocity) / time.

However, since time (2 hours) was given in a different unit than velocity which was meter per second, we need to convert 2 hours into seconds.
1 hour = 3600 seconds
So, 2 hours = 2 x 3600 = 7200 seconds

Using the above formula and values: acceleration = (8 m/s - 0 m/s) / 7200 seconds = 0.0011 m/s².

So, the average acceleration of the horse, assuming it started from rest, is approximately 0.0011 m/s².
