Answer:
PE = 882 J
Explanation:
Through the International System we know that the gravity of the earth is 9.8 m/s², so...
Data:
- m = 45 kg
- g = 9.8 m/s²
- h = 2 m
- PE = ?
Formula:
- [tex]\boxed{\bold{PE=m*g*h}}[/tex]
Replace and solve:
- [tex]\boxed{\bold{PE=45\ kg*\ 9.8\frac{m}{s^{2}}*2\ m}}[/tex]
- [tex]\boxed{\boxed{\bold{PE=882\ J}}}[/tex]
The potential energy of the sled is 882 Joules.
Greetings.
