A cart is loaded with a 3-kg rice and pulled at constant speed along an inclined plane to the height of a seat- top. If the height of the seat top is 0.45 meters,
then a) what is the potential energy of the loaded cart at the height of the seat-top?


Sagot :

Answer:-

  • Mass=m=3kg
  • Height=h=0.45m
  • Acceleration due to gravity=g=10m/s^2

We know

[tex]\boxed{\sf E_P=mgh}[/tex]

[tex]\\ \sf\longmapsto E_P=3\times 0.45\times 10[/tex]

[tex]\\ \sf\longmapsto E_P=1.35\times 10[/tex]

[tex]\\ \sf\longmapsto E_P=0.135J[/tex]
