The coordinates of a bird flying in the xy-plane are given by x(t)=αt and y(t)=3.0m−βt2, where α=2.4m/s and β=1.2m/s2.part a: calculate the velocity vector of the bird as a function of time. give your answer as a pair of components separated by a comma. for example, if you think the xcomponent is 3 and the y component is 4, then you should enter 3,4.
part b: calculate the acceleration vector of the bird as a function of time. give your answer as a pair of components separated by a comma. for example, if you think the x component is 3 and the y component is 4, then you should enter 3,4
