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
m=0.0153kg <----------- answer
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?
