A particle moves in a plane according to the following position coordinates as a function of time: ()=0.302+7.0+20 and ()=0.3029.0+30 ; x and y in meters and t in seconds. At time =2.0 , get the vectors: (a) position () (b) velocity () (c) acceleration ().

The answers are: .=(32,8+13,2); .=(5,87,8)/s; .=(0,6+0,6)^2
