radius= .4m
wi=25/.4 wf= 35/.4
angacceleration= (wf-wi)/time
wi=25/.4 wf= 35/.4
angacceleration= (wf-wi)/time

From the Eqn of motion we have: v=u+at
=25+35*6
=360m/s
recall that angacceleration=v^2/r
r=40m,
=360^2*40
=3240m/s^2
=25+35*6
=360m/s
recall that angacceleration=v^2/r
r=40m,
=360^2*40
=3240m/s^2
