The standard metric unit on electric potential difference is the volt, abbreviated V and named in honor of Alessandro Volta. One Volt is equivalent to one Joule per Coulomb.
If there are no forces acting upon the object, then there is no acceleration. If there is no acceleration, then the object will move with a constant velocity.
KE=1/2mv^2 - equation for kinetic energy KE=(1/2)(0.12 kg)((7.8 m/s)^2 - plug it into the formula KE=(0.06 kg)(60.84 m/s) - multiply 1/2 to the mass and square the speed KE= 3.7 J - answer Hope this helps
