QUESTION
Calculate the force if
k
=
150
N
/
m
k = 150 \, N/m
k
=
150
N
/
m
and
x
=
−
0.3
m
x = -0.3 \, m
x
=
−
0.3
m
.
QUESTION
Calculate the displacement if
F
s
=
−
40
N
F_s = -40 \, N
F
s
=
−
40
N
and
k
=
80
N
/
m
k = 80 \, N/m
k
=
80

QUESTION
Find the displacement if
F
s
=
−
10
N
F_s = -10 \, N
F
s

−
10
N
and
k
=
50
N
/

ANSWER
x
=
0.2
m
x = 0.2 \, m
x
=
0.2
m
. From
x
=
F
s
−
k
=
−
10
−
50
=
0.2
x = \frac{F_s}{-k} = \frac{-10}{-50} = 0.2
x
=
−
k
F
s
=
−
50
−
10
=
0.2
m.
