When riding a roller coaster , you go up and down many hills. when do you have the maximum kinetic energy ?

it should be when you’re going down the highest hill

Explanation:

The reasoning behind this is; your potential energy is the energy you have when you’re, let’s say at the peak of the roller coaster, your potential energy (energy that is not yet in use but COULD be) determines the amount of kinetic energy possible, so you’re at the highest peak, you have the most potential energy therefore giving you the most kinetic energy! Hope this helps a bit

the invasive species was introduced due to commercial purpouses, as there was a demand for fur clothes and hence, a business opportunity connected to this product. actually, it was when the nutrias scaped, causing harm to the us ecosystems when they acquired the status of invasive species. in this case they have caused an environmental problem, but it could have affected also economic interests or even human health.
