Problems

`8-9`

refer to the following situation and figure. Two blocks of mass

`m_(1)=6.3kg`

and

`m_(2)=2.5kg`

are connected by a rope that goes over a pulley and provides a tension

`T.m_(1)`

is on an inclined plane with an angle

`\theta _(1)=60\deg `

and a kinetic friction coefficient

`\mu _(k)=0.2.m_(2)`

is on an inclined plane with an angle

`\theta _(2)=30\deg `

and a kinetic friction coefficient

`\mu _(k)=0.2`

. Problem 8: What is the acceleration of the system? a.

`3.0(m)/(sec^(2))`

b.

`3.5(m)/(sec^(2))`

c.

`4.0(m)/(sec^(2))`

d.

`4.5(m)/(sec^(2))`

Problem 9: What is the tension of the rope? a. 20.2 N b. 25.2 N c. 30.2 N d. 35.2 N
