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
