How did u find the antiderivative

Rohan Joshi - 5 months ago

I didn't have a specific method in mind when I came up with the question, I thought that it would be easy to spot the anti-derivative based on the terms directly.

Ahh never mind I got it. You found the function whose gradient is the force, and just calculated the change in the value of the function.
