Answer:
Formula for Potential energy is given by:
[tex]\text{P.E} = mgh[/tex]
where,
m is the mass
g is the gravity i.e, g = 9.8 m/s^2
h is the height.
As per the statement:
An apple with a mass of 0.95 kilograms hangs from a tree branch 3.0 meters above the ground.
⇒ m = 0.95 kg and h = 3 meter
Using formula we have;
P.E = mgh
Substitute the given values we have;
P.E = (0.95)(9.8)(3) = 27.930 kg m^2/s^2
USe: [tex]\text{1 kg m}^2/{s^2} = J[/tex]
Therefore, the potential energy of the apple is, 27.930 J
