Answer :
Final answer:
The pair of horses completed a total work of 25,925 Joules.
Explanation:
To calculate the work done by the pair of horses, we can use the formula:
Work = Force x Distance x cos(theta)
Given that the acceleration of the plow is 0.5 m/s^2, we can find the force using Newton's second law:
Force = mass x acceleration
Substituting the values, we get:
Force = 425 kg x 0.5 m/s^2
= 212.5 N
Now we can calculate the work:
Work = 212.5 N x 122 m x cos(0)
Since cos(0) = 1, the work done by the pair of horses is:
Work = 212.5 N x 122 m x 1
= 25,925 Joules
