It takes #"3400 N"# to raise the 25-kg body to a height of 14 m

Explanation:

#"Work"="force"xx"distance"#

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

#"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.)

#"Work"=245"N"xx14"m"#

#"Work"=3400"N·m"=3400"Joules"# (rounded to two significant figures)
