How much work does it take to raise a #9 kg # weight #12 m #?

Answer 1

#1058.4# joules

Since the weight is being raised, the weight's total energy transferred (or work done) will be equal to its increased gravitational potential energy.

The gravitational potential energy can be found using this formula:

#"GPE"=mgh#

where:

#m# is the mass of the object in kilograms
#g# is the gravitational acceleration, which is around #9.8 \ "m/s"^2# on Earth
#h# is the height raised in meters

Thus, we obtain:

#"GPE"=9 \ "kg"*9.8 \ "m/s"^2*12 \ "m"#
#=1058.4 \ "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.
