A certain Force applied to a particle of m1 gives it an acceleration of 20m/s2. The same Force applied to a particle of m2 gives it an acceleration of 30m/s2. If the two particles are glued together and the same force is applied to the combination, find the acceleration.
The Attempt at a Solution
m2/m1=a2/a1 would be helpful if a mass was given. No idea how to set up this problem.
