Imagine a book that is falling from a shelf. At a particular moment during its fall, the book has a kinetic energy of 25 J.
What was the initial potential energy of the book, and what is its total kinetic energy at the instant just before it strikes the floor?

mass and volume are the answers you are looking for

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
