An orange of mass 40g falls freely from the tree to the ground through a distance of 2.5m. Calculate the potential energy of the orange before it hits the ground. g=10m/s²

g is not 10m/s^2 anywhere on Earth.
Frankly, I like to call g not the acceleration due to gravity, but the Gravity Field
Gravity Field= 9.8Newtons/kilogram or 9.8N/kg
PE=massinKg*GravityField*height=.04kg*9.8N/kg*2.5m=...
remember that a N-m is a joule, by definition.
