[Free] The coordinates of a bird flying in the xy-plane are given by [tex]x(t) = \alpha t[/tex] and [tex]y(t) = 3.0 \, \text{m} - \beta t^2[/tex], where [tex]\alpha = 2.4 \, \text{m/s}[/tex] and [tex]\beta = 1.2 \, \text{m/s}^2[/tex]. 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 x component 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.
