3. Andy runs 436.8 meters in 62.08 seconds. a. If Andy runs at a constant speed, how far does he run in one second? Give your answer to the
nearest tenth of a second.
b. Explain why your answer to part A makes sense.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v

answer is because 4×10=40

and 98×4= is 392

40,392

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
