Part A

The disk starts from rest and is given an angular acceleration

$\backslash$alpha $=(2$t$^(2))$ra$($d$)/($s$^(2)),$ where t is in seconds.

$($Figure $1)$

Determine the angular velocity of the disk when t$=1$s$.$

Express your answer to three significant figures and include the appropriate units.

Part B

Determine the angular displacement of the disk when t$=1$s$.$

Express your answer to three significant figures and include the appropriate units.
