Using a forked rod, a $0\mathrm{.}65-kg$ smooth peg $P$ is forced to

move along the vertical slotted path $r=(0\mathrm{.}5)m,$ where

$$ is in radians. The angular position of the arm is

$=(\frac{}{8}{t}^2)rad$ where $t$ is in seconds. The peg is in

contact with only one edge of the rod and slot at any

instant. $($Figure $1)$
