A2kg block and an 8kg block are connected by a relaxed horizontal spring with spring-constant 300n/m. you pull the 8kg block with some constant horizontal force. there is a coefficient of kinetic friction between the blocks and the floor of μk = 0.3. after a time, the spring is stretched a certain constant amount, and the system moves with constant velocity. (a) draw free-body diagrams for both blocks. (b) what pulling force did you apply? (c) how much is the spring stretched?

Did the proton move into a region of higher potential or lower potential? did the proton move into a region of higher potential or lower potential? because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of lower potential to a region of higher potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential.request answerpart bwhat was the potential difference that stopped the proton? express your answer with the appropriate units.î”v î” v = nothingnothingrequest answerpart cwhat was the initial kinetic energy of the proton, in electron volts? express your answer in electron volts.ki k i = nothing ev request answerprovide feedback
