1. The problem statement, all variables and given/known data The diagram shows a potato launcher before the spring is compressed and used to launch a potato. A force of 65 N is required to compress the spring 5 cm. The spring will be compressed 10 cm before the potato is inserted. The inside of the tube and the potato skin have a kinetic coefficient of 0.15 . The potato has a mass of 180g. What is the maximum range of the potato if it launched at 50 degrees with respect to the horizontal? You may ignore air resistance. 2. Relevant equations Eo + Ef = W(non conservative) (PEo + KEo) + (PEf + KEf) = W(non conservative) F = ma Vf = Vo + at Vf^2 = Vo^2 + 2aΔx 3. The attempt at a solution So what I did is drew an free body diagram of the potato before launch, the distance the potato will be traveling along the launcher would be 1m if the spring was compressed 10cm, so what that said I applied Work with non conservative force equation [(PEo + KEo) + (PEf + KEf) = W(non conservative)] , correct me if I am wrong but I replaced the potential energy with the Spring force equation which is Fs = -kx with k being equal to 65N, I then solved for Vf which im assuming will get me the range of how far the object will go maybe by using a kinetic equation, but I don't see how I can do that. Am I looking for the final velocity which will get me the distance or is there something else I need to find. thanks for any/all your input!
