During launches, rockets often discard unneeded parts. a certain rocket starts from rest on the launch pad and accelerates upward at a steady 3.10 m/s^2. when it is 240 m above the launch pad, it discards a used fuel canister by simply disconnecting it. once it is disconnected, the only force acting on the canister is gravity (air resistance can be ignored). a)how high is the rocket when the canister hits the launch pad, assuming that the rocket does not change its acceleration?
b)what total distance did the canister travel between its release and its crash onto the launch pad?

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
