What is the gravitational potential energy of a # 29 kg# object on a shelf # 5/6 m # high?

Answer 1

Nathan Ashcroft

237.075 Joules

The gravitational potential energy #(U)# is given by:

#U=mgh#

wherein

#m# is the mass of the object,

#g# is the acceleration due to gravity, #=9.81m/s#

and #h# is the object's height above the ground.

Changing the specified values in the equation above,

#U=29*9.81*5/6#

#U=237.075 J#

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.
