A simple Atwood's machine uses two masses, m1 and m2. Starting from rest, the speed of the two masses is 8.0 m/s at the end of 4.0 s. At that instant, the kinetic energy of the system is 60 J and each mass has moved a distance of 16.0 m. Determine the values of m1 and m2.

The optimistic view of human nature held by supporters of the humanistic perspective led to more positive views of human nature throughout the field of psychology.t or f?

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
