A horse gallops around a circular arena. The centripetal force on the horse is directed inward towards the center of the arena. tangent to the circular path directed outward away from the center of the arena equal to 9.8

## Step 1<br />The problem involves understanding the concept of centripetal force. Centripetal force is the force that keeps an object moving in a circular path. It is always directed towards the center of the circle.<br /><br />## Step 2<br />In this case, the horse is galloping around a circular arena. The force that keeps the horse moving in this circular path is the centripetal force.<br /><br />## Step 3<br />Therefore, the direction of the centripetal force on the horse is inward, towards the center of the arena.
