QUESTION
What is the potential energy of a 10 kg object at ground level?
QUESTION
Find the potential energy of a spring with
k
=
150
N/m
k=150 \, \text{N/m}
k
=
150
N/m
and
x
=
0.05
m
x=0.05 \, \text{m}
x
=
0.05
m

ANSWER
Potential energy is
0.1875
J
0.1875 \, \text{J}
0.1875
J
. Using

2
(
150
)
(
0.05
)

=
0.1875
PE_s = \frac{1}{2}(150)(0.05)^2 = 0.1875
