Problems
6-7
refer to the following situation and figure. A mass
m_(1)
and a mass
m_(2)
are swung around in a vertical circle. As
m_(1)
and
m_(2)
go around the vertical circle, they stay along the same line. The mass
m_(1)=3kg
is swung around the vertical circle with a rope that has a tension
T_(1)
and a length
L=0.5m
. The mass
m_(2)=4kg
is attached to
m_(1)
by a rope that has a tension
T_(2)
and a length
L=0.5m
. At the top of the motion, as shown in the figure below,
m_(1)
has a speed
v_(1)=4(m)/(sec)
and
m_(2)
has a speed
v_(2)=8(m)/(sec)
. Problem 6: What is the tension
T_(1)
at this instant? a. 223.4 N b. 243.4 N c. 263.4 N d. 283.4 N Problem 7: What is the tension
T_(2)
at this instant? a. 216.8 N b. 236.8 N c. 256.8 N d. 276.8 N
