A wheel released from rest is rotating with constant angular acceleration of $2\mathrm{.}2ra\frac{d}{s^2}.$ At $1\mathrm{.}5$ s after release,

what is its angular velocity $?$

$=$

through what angle $$ has the wheel turned?

$=$

how many revolutions, $N,$ has it made?

$N=$

what is the linear speed $v_t$ of a point $0\mathrm{.}4$ m from the axis of rotation?

$v_t=$

$\frac{m}{s}$

what is the magnitude $a_1$ of the linear acceleration of the same point?

$a_t=$

$\frac{m}{s^2}$
