A spy needs to climb the outside of a castle in Latvia (don't ask why—if I told you I'd have to kill you). So
he throws one of those cool hooks they use in movies
to climb up walls. Our spy's top throwing velocity for
the 4-pound hook is 74 feet per second, and he releases
it from a height of 3 feet. Will the hook reach over the
castle wall, which is 80 feet high?

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
