Answer 1

Answer:

Angular velocity=2.072

Linear speed= 2.03

Centripetal acceleration =4.02

Explanation:

:Angular velocity

W=thita /t= 20*2¶/60=2.072

:Linear speed = v=w*r = calculating from w=n*2¶r/60

2*2¶*r/60=2.072

r=0.98

Putting in linear speed formula v=w*r

V=2.072*0.98=2.03

:Now centripetal acceleration =ac = v^2/r

2.03*2.03/0.98

=4.20
