Answer 1

Explanation:

A point on a wheel rotates about its center according to the relation Theta = 6t – 2t^3.(i) Find the average angular velocity of a point on the wheel during a time in which it comes to rest (in rad/s).

a)2 c)4

b)3 d)0.5

(ii) Find angular acceleration averaged over the time from starting till the point stops.

a)-6 c)-3

b)-2 d)-1
