Final answer:
The work done by the elephant on the circus wagon is calculated by multiplying the force applied (200 N) by the distance moved (20 m), giving us 4000 J (joules).
Step-by-step explanation:
The question asks us to calculate the work done by an elephant while moving a circus wagon. Work is defined as the product of the force applied in the direction of motion and the displacement of the object (W = Fd). Here, the pulling force is 200 N and the distance moved is 20 meters. Assuming that the direction of the force is the same as the direction of motion, we can use the formula W = F × d to calculate the work done, without needing to consider the angle (since it is 0 degrees).
So, the work done by the elephant is:
W = F × d = 200 N × 20 m = 4000 J (joules).
