The potential energy of the cart loaded with a brick and that is pulled at constant sped along an inclined plane to a height of 0.45 meters, is 13.24 J.
At the height of the seat-top, the potential energy is given by:
[tex] E_{p} = mgh [/tex]
Where:
g: is the acceleration due to gravity = 9.81 m/s²
m: is the mass of the loaded cart = 3.0 kg
h: is the height = 0.45 m
Hence, the potential energy is:
[tex] E_{p} = mgh = 3.0 kg*9.81 m/s^{2}*0.45 m = 13.24 J [/tex]
Therefore, the potential energy of the loaded cart at the height of the seat-top is 13.24 J.
