Homework Statement
a muon moving in a straight line enters a region w/ speed of 5 x 10^6 m/s. it then slowed down at a rate of 1.25 m/s^2. how far does the muon take to stop??
Homework Equations
2ad + square of initial velocity = square of final velocity
The Attempt at a Solution
my answer was 1 x 10 ^13 m...
i substituted the given (acceleration, initial velocity, and the final velocity which is 0) to the equation, then i got that displacement...
my prof told me that the answer must be 0.1 m,,
i don't know why,,, is it something about the behavior of muon??
or if isn't,, is there something wrong in the given??
thx ,,, i really need this asap... thanks again!
