What are Newtons laws?
OK, with the penny, what forces are acting on it it the first place? What happens to disturb this equilibrium? (clue, one of the forces changes). What happens to the coin (note, this is in at least two stages and different forces are involved).
Answer these questions and you should be able to apply Newton's laws and answer your own question.

a) Mary status on the floor will word that the field does no longer flow alongside with the truck, so there will be no accelleration or flow with appreciate to her. yet as quickly because it slides out under the shifting truck, it extremely is going to fall, it is, accellerate downwards to earth at a tension of f=m.a, the place a = 9.8m/s^2. whilst it hits the floor, it extremely is going to decellerate very rapidly, to attain a velocity of 0m/s with appreciate to the floor. b) Chris will word that the field (and Mary) accellerates remote from him, at a value equivalent to, yet in an other way, because of the fact the accelleration of the truck with appreciate to a mounted element on the floor the place to truck used to stand. there is additionally a short factor to downward accelleration (and then deccelleration) because of the fact the field falls, as defined under (a).

an object at rest has a tendency to stay at rest. an object in motion tends to stay in motion, until it hits an object of greater mass.
