The speed of a particle doubles and then doubles again because a net external force acts on it. Does the net force do more work during the first or the second doubling? Justify your answer.
I'm not sure, but i think E = 1/2 mv(squared)
The Attempt at a Solution
Im pretty sure this has something to do with kinetic energy, but the question is asking about the net force doing work. How do I incorporate force into this?
