For an extended object, I think there is a delay in the acceleration of the C of M -- the delay is due to the finite speed of sound.
bc, naive?
p.s. Would there also be a delay at the front from the electrostatic repulsion (contact) -- here a bit shorter related to C?
p.p.s. I do believe N laws are symmetrical and imply nothing and work as such macroscopically -- microscopically?
