QUESTION
Find the total initial momentum if
m
1
=
0.50
kg
m_1=0.50\,\text{kg}
m
1
=
0.50
kg
at
+
0.80
m/s
+0.80\,\text{m/s}
+
0.80
m/s
and
m
2
=
0.50
kg
m_2=0.50\,\text{kg}
m
2
=
0.50
kg
at

ANSWER
p
i
=
0.30
kg
⋅
m/s
p_i=0.30\,\text{kg}\cdot\text{m/s}
p
i
=
0.30
kg
⋅
m/s
.
p
i
=
(
0.50
)
(
0.80
)
+
(
0.50
)
(
−
0.20
)
=
0.40
−
0.10
=
0.30
p_i=(0.50)(0.80)+(0.50)(-0.20)=0.40-0.10=0.30
p
i
=
(
0.50
