Age structure diagrams show the distribution of people of various ages. the diagrams also show the number of people in the prereproductive, reproductive, and postreproductive years. research and note what else you can infer from age structure diagrams.

The acceleration of the horse as it came to a stop is .

Explanation:

Given that,

Initial speed of the horse and rider, u = 21 m/s

It finally comes to rest, v = 0

The horse slows down for 52 m with constant acceleration before it stops.

We need to find the acceleration of the horse as it came to a stop. Let a is the acceleration. We can find it using third equation of motion as :

We need to find the acceleration of the horse as it came to a stop. Let a is the acceleration. We can find it using third equation of motion as :

So, the acceleration of the horse as it came to a stop is . Negative sign shows deceleration.
