# What is the largest mass that can be placed on the spring

jaron

## Homework Statement

the spring in a typical hooke's law apparatus has a force constant of 1.50 N/m and a maximum extension of 10cm. what is the largest mass that can be placed on the spring without damaging it?

## Homework Equations

what i believe to be relevant:
F=-kx
W=F"d
E=mg(h)

## The Attempt at a Solution

F=1.5(0.10)
F=0.15

W=F"d
W=0.15(0.10)
W=0.015J

0.015=m(9.81)(0.10)
0.015/0.981=m

now i have no idea how this can be wrong.. i have gone over it many times now.
my textbook has it as 0.153kg.
am i right on this one?
