Question

A farmer lifts his hay bales into the top loft of his barn by walking his horse forward with a constant velocity of 8 ft/s. Determine the velocity and acceleration of the hay bale when the horse is 10 ft away from the barn.

Answer 1

The velocity of the hay bale is 8 ft/s when the horse is 10 ft away from the barn. The acceleration of the hay bale is zero.

Step-by-step explanation:

To determine the velocity of the hay bale when the horse is 10 ft away from the barn, we need to first calculate the time taken by the horse to cover that distance. The velocity of the horse is given as 8 ft/s, and since the distance is 10 ft, the time taken can be calculated using the formula: time = distance / velocity. So, time = 10 ft / 8 ft/s = 1.25 s.

Since the horse is moving with a constant velocity, the velocity of the hay bale will also be 8 ft/s when the horse is 10 ft away from the barn.

The acceleration of the hay bale is zero because there is no change in its velocity.
