A body is falling under gravity. When it loses a gravitational potential energy by $U$, its speed is $v$. The mass of the body shall be (a) $\frac{2 U}{v}$ (b) $\frac{U}{2 v}$ (c) $\frac{2 U}{v^{2}}$ (d) $\frac{U}{2 v^{2}}$
An object of mass m falls from rest in a vacuum. As it falls it losses an amount E of gravitational potential energy. What is the speed of the object then?
