Question $1$

The system is released from rest when the angle $\backslash$theta $=90$ dog. Determine the angular velocity

of the uniform slender bar when $\backslash$theta $=60$deg.

Use the values:

m$1=1\mathrm{.}43$kg

m$2=3\mathrm{.}69$kg

b$=1$m

Give your answer to two decimal places; use $9\mathrm{.}81($m$)/($s$^(2))$ for g $.$

Question $2$

How much non$-$conservative work is done in J$=$N$^(\text{'})$m $?$

Question $3$

How much initial kinetic energy is there in J$=$N$\backslash$deg m $?$

Question $4$

What is the relationship of the magnitude of the y velocity of mass $2$ to the magnitude of the

tangential velocity of point A at $\backslash$theta $=$B deg?

hat$($y$)=$x$*$bhat$(\backslash$theta $)$

What is x $?$

Hint: Find the length of the rope for any angle $\backslash$theta $,$ take a derivative with respect to time to get

a velocity relationship, and then plug in A$.$
