To calculate the work required, we need to multiply the force applied by the dog by the distance traveled. We can assume that the force applied by the dog is equal to its weight, which is given by the equation:
Force = mass x gravity
The mass of the dog is 30 kg and the acceleration due to gravity is approximately 9.8 m/s^2. So the force applied by the dog is:
Force = 30 kg x 9.8 m/s^2 = 294 N
Now we can calculate the work:
Work = force x distance = 294 N x 50 m = 14700 Joules
Therefore, the correct answer is B) 1500 Joules.
