2.000
0.0 m/s
Answer
PE = m*g*h
g=9.8 m/s/s
m=0.200 kg
h=2.000 m
so
PE=3.920 J
Answer
KE=.5*m*v^2
m=0.2 and
v=0.0 so
KE = 0 J
Answer
TME=PE+KE
PE=3.920 J
KE=0 J
so
TME=3.920 J
1.490
Answer
First find PE,
then KE, then
speed. Since
KE=.5*m*v^2,
v=SQRT(2*KE/m).
With KE=1.00 J
m=0.200 kg
Find
v = 3.162 m/s.
Answer
PE = m*g*h
g=9.8 m/s/s
m=0.200 kg
h=1.490 m
so
PE=2.920 J
Answer
TME=PE+KE
So
KE = TME - PE
TME = 3.920 J
PE=2.920 J so
KE = 1.000 J
3.920 J
1.128
Answer
Find PE, KE,
then speed.
KE=.5*m*v^2, so
v=SQRT(2*KE/m).
KE=1.709 J and
m=0.200 kg
So v = 4.134 m/s.
Answer
PE = m*g*h
g=9.8 m/s/s
m=0.200 kg
h=1.128 m
so
PE=2.211 J
Answer
TME=PE+KE
So
KE = TME - PE
TME = 3.920 J
PE=2.211 J so
KE=1.709 J
Answer
TME is
conserved.
It will be
the same
as it was
initially:
3.920 J.
0.897
Answer
Find PE, KE,
then speed.
KE=.5*m*v^2, so
v=SQRT(2*KE/m).
KE=2.172 J and
m=0.200 kg, so
v = 4.660 m/s.
Answer
PE = m*g*h
g=9.8 m/s/s
m=0.200 kg
h=0.897 m
so
PE=1.748 J
Answer
TME=PE+KE
So
KE = TME - PE
TME = 3.920 J
PE=1.748 J so
KE=2.172 J
Answer
TME is
conserved.
It will be
the same
as it was
initially:
3.920 J.
0.357
Answer
Find PE, KE,
then speed.
KE=.5*m*v^2, so
v=SQRT(2*KE/m).
KE=3.220 J and
m=0.200 kg, so
v = 5.675 m/s.
Answer
PE = m*g*h
g=9.8 m/s/s
m=0.200 kg
h=0.357 m
so
PE=0.700 J
Answer
TME=PE+KE
So
KE = TME - PE
TME = 3.920 J
PE=0.700 J so
KE=3.220 J
Answer
TME is
conserved.
It will be
the same
as it was
initially:
3.920 J.
