1] a stone is thrown horizontally with the velocity of 15m/s. determine the tangential and normal accelerations of the stone in 1sec after it begans to move.2] a partical moves in x-y plane with the velocity v= (a)i + (bt)j. at the instant t=a(sqrt3)/b themagnitude of tangential , normal and total acceleration are ____, _____, and _____.3] a partical moves in a circle of radius R with a constant speed v. then find the magnitude of average acceleration during the time interval [(pie)R/2v].
