Answer
To calculate the change in gravitational potential energy (GPE) of the apple as it falls, we can use the following formula:
where:-
is the change in gravitational potential energy,-
is the mass of the apple,-
is the acceleration due to gravity,-
is the height from which the apple falls.Given:-
kg (mass of the apple),-
(acceleration due to gravity),-
m (height from which the apple falls).Now, let's plug these values into the formula:
Rounding to the nearest hundredth, the change in gravitational potential energy of the apple is:
Answer: The change in gravitational potential energy of the apple is approximately 1.72 Joules.
