find the acceleration of a 3 kg mass as it moves with a constant speed of 4 m/s along a circle of radius 2 m.

only acceleration is centripetal, toward the center = v^2/r = 16/2 = 8 m/s^2
This has nothing to do with the mass just as the previous question had nothing to do with the material being copper.
