If a Cu 2 + ion that is initially at rest accelerates through a potential difference of 12 V without friction, how much kinetic energy will it gain?

When calculating gravity between 2 objects, where should the distance be measure from?

An object is moving initially with a velocity of 4.7 m/s. After 3.9 s the object's velocity is - 2.1 m/s. What is the object's average acceleration during this time? I believe that the vf is - 2.1 m/s vi should be 4.7 m/s and the t should be 3.
