ANSWER:
The potential energy of the book is 245 J.
SOLUTION:
We are given the following:
- mass m = 10 kg
- height above a reference point h = 2.5 m
Use the formula for potential energy. ( g = 9.8 m/s² )
[tex] \qquad {\boxed{\sf P.E._{grav} = m \times g \times h}} [/tex]
- [tex] \sf P.E._{grav} = (10\:kg) \times (9.8\: \frac{m}{s^2}) \times (2.5\:m) [/tex]
- [tex] \sf P.E._{grav} = (10\:kg) \times (24.5\: \frac{m^2}{s^2}) [/tex]
- [tex] \sf P.E._{grav} = {\boxed{\sf {245\:J}}} [/tex]
Therefore, the potential energy of the book is 245 J.
