# How much work does it take to raise a 25 kg  weight 14 m ?

Dec 17, 2015

It takes $\text{3400 N}$ to raise the 25-kg body to a height of 14 m

#### Explanation:

$\text{Work"="force"xx"distance}$

In this case, the force is the weight in Newtons.

$\text{Force"_"weight"=mxxg=25"kg"xx9.81"m/s"^2="245 N}$
(I will round the final answer to two significant figures at the end.)

$\text{Work"=245"N"xx14"m}$

$\text{Work"=3400"N·m"=3400"Joules}$ (rounded to two significant figures)
