Question $1$

The system is released from rest when the angle $=90$deg. Determine the angular velocity

of the uniform slender bar when $=60$deg.

Use the values:

$m1=1\mathrm{.}37kg$

$m2=3\mathrm{.}24kg$

$b=0\mathrm{.}9m$

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

Question $2$

How much non$-$conservative work is done in $J=N^{*}m?$

Question $3$

How much initial kinetic energy is there in $J=N^{*}m?$

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 $=36$deg $?$

$y^{}=x*b{}^{}$

What is x $?$

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

a velocity relationship, and then plug in $.$
