1.	A wheel rotates around a stationary axis so that rotation angle thetavaries as theta= pt^(2) where p=0.2"rad"//"sec"^(2) The total acceleration (a) of the point A at the rim at the moment t = 2.55sec. If linear velocity of the point (A) at this moment is V = 0.65m//sec is
Answer» `0. 7 m//sec^(2)` `0.6 m//sec^(2)` `0.5 m//sec^(2)` `0.4 m//sec^(2)` ANSWER :A
