Answer: 98,000 J
Explanation: The total energy or mechanical energy is expressed in the following equation:
ME= PE + KE
PE = mgh
= 1000 kg x 9.8 m/s² x 10m
= 98000 J
ME = PE - KE
= 98000 J - 0 J
= 98000 J
Potential energy is the energy of the body due to its position. The total energy of the car is 98000 J.
The total energy of the car is the sum of its static and kinetic energy. It can be calculated by the formula,
[tex]E = PE + KE[/tex]
Where,
[tex]E[/tex]- Total energy
[tex]PE[/tex] - Potential energy
[tex]KE[/tex] - Kinetic energy
Potential energy can be calculated by the formula,
[tex]PE = mgh[/tex]
Where,
[tex]m[/tex]- mass of the car
[tex]g[/tex] - gravita tional acceleration
[tex]h[/tex] - height
Put the value in the formula,
[tex]= 1000\rm\ kg \times 9.8 \rm \ m/s^2 \times 10\rm \ m\\\\= 98000 J[/tex]
Since the car is not moving hence the kinetic energy will be zero.
Therefore, the total energy of the car is 98000 J.
