1. The problem statement, all variables and given/known data A single constant force F = (3i + 5j) N acts on a 4.00 kg particle. Calculate the work done by this force if the particle moves from the origin to the point having the vector position r = (2i - 3j)m. 2. Relevant equations W= Fr Wg= mgy1-mgy2 Wc= Ui - Uf 3. The attempt at a solution First I converted the friction and position coordinates to a single number. Then I tried to simply multiply the force and position but it was incorrect. The equations my book gave me was for gravity, spring, and potential but I feel like these equations don't fit in with the problem. What am I doing wrong? Thank you for your time!
