Please, since, constant force F = dp/dt = ma, how can I find
mathematically the constant acceleration a of an object if I know its
mass is m, its displacement is x, and the time is t? What if the mass
is 2m, or m/2, and the displacement x/2, or 2x, while the time remains
the same t? Thank you. |

You should probably be asking this in a physics newsgroup.
But since you're here, what do you know about the
relationships between acceleration, velocity, and
distance?

I know that a(t) = d^2 x/dt^2. |

So, if you were to start with acceleration, how would
you find the velocity with respect to time? Then, from
velocity, how would you find the distance? (Hint: you
need to consider antidifferentiation (integration)) |
