The potential energy of the book held 2.0 m above the ground can be calculated using the formula for gravitational potential energy:
( PE = mgh )
Where: ( m = 2.5 , kg ) (mass of the book) ( g = 9.8 , m/s^2 ) (acceleration due to gravity) ( h = 2.0 , m ) (height above the ground)
Substituting the values:
( PE = (2.5 , kg) \times (9.8 , m/s^2) \times (2.0 , m) )
( PE = 49 , J )
So, the potential energy of the book held 2.0 m above the ground is 49 joules.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
