Answer: The correct answer is 0.735 J.
Explanation:
The expression for the potential energy is as follows;
PE= mgh
Here, m is the mass of the object, g is the acceleration due to gravity and h is the position.
It is given in the problem that an acorn with a mass of .0300 kilograms is hanging from a branch in a tree. It is 2.50 meters from the ground.
Calculate the potential energy of the acorn.
Put m= .0300 kg, g= 9.8 m/s^2 and h= 2.50 m in the above expression.
PE= ( .0300)( 9.8)(2.50)
PE =0.735 J
Therefore, the potential energy of the acorn is 0.735 J.
