QUESTION
Find the total mechanical energy if KE = 50 J and PE = 30 J.
QUESTION
Calculate the elastic potential energy for
k
=
200
N/m
k = 200 \text{ N/m}
k
=
200
N/m
and
x
=
0.1
m
x = 0.1 \text{ m}
x
=
0.1
m
.

ANSWER
W
=
60
J
W = 60 \text{ J}
W
=
60
J
. Using
W
=
F
d
cos
(
0
°
)
=
(
20

(
1
)
=
60
W = Fd\cos(0°) = (20)(3)(1) = 60
W
=
F
d
cos
(
