Final answer:
The work done in moving a 1500kg cow 30cm with a 4000 newton force is 1200 joules.
Step-by-step explanation:
To find the work in joules produced moving a 1500kg cow 30cm with a 4000 newton force, we can use the formula Work = Force x Distance, where the force is in newtons and the distance in meters.
First, we need to convert the distance from centimeters to meters by dividing by 100. Therefore, 30cm is 0.3 meters.
Using the formula:
Work = 4000N x 0.3m
= 1200 Joules.
This is the work done in moving the cow over the specified distance with the given force.
