Answer:
[tex]\boxed {\boxed {\sf882 \ Joules}}[/tex]
Explanation:
Potential energy can be found by multiplying the mass by the height by the gravitational acceleration.
[tex]PE=mgh[/tex]
The mass is 45 kilograms. The height is 2 meters. The gravitational acceleration on Earth is 9.8 meters per seconds squared.
[tex]m=45 \ kg \\h= 2 \ m \\g=9.8 \ m/s^2[/tex]
Substitute the values into the formula.
[tex]PE=45 \ kg * 2 \ m * 9.8 m/s^2[/tex]
Multiply.
[tex]PE=441 kg*m/s^2*2 \ m[/tex]
[tex]PE= 882 \ kg *m/s^2 *m[/tex]
1 kg*m/s^² is equal to 1 Newton (N). Substitute N in for kg*m/s²
[tex]PE=882 \ N*m[/tex]
1 Newton meter (N*m) is equal to 1 Joule (J). Our current answer is equivalent to 882 Joules.
[tex]PE= 882 \ J[/tex]
The sled's potential energy is 882 Joules.
