Block A with a mass m $1$ and block B with a mass m $2,$ are hung from the ceiling of an elevator by

ropes $1$ and $2.$ The system is accelerating downward with acceleration of magnitude g$/2.$ Determine

the tension in rope $1.$

A$.$ T $1=1$

$2$ m $1$ g

B$.$ T $1=(1$

$2$ m $1$ m $2)$g

C$.$ T $1=(1$

$2$ m $2$ m $1)$g

D$.$ T $1=3$

$2$ m $1$ g

E$.$ T $1=$ m $1$ g

$10.$ Which of the following statements is$($are$)$ true if an object moving under constant acceleration

a $6=0$ with an initial velocity v $06=0$ continues to move in the same direction as v $0$ for all time t $0.$

A$.$ This only happens if v $0>0$ and a $>0.$

B$.$ This only happens if v $0>0$ and a $0.$

C$.$ v $0$ and a have the opposite sign.

D$.$ v $0$ and a have the same sign.

E$.$ None of the above
