CALC? A bird flies in the xy-plane with a velocity vector given by and ? = 4.0 m/s2. The positive y-direction is vertically upward. At t = 0 the bird is at the origin. (a) Calculate the position and acceleration vectors of the bird as functions of time. (b) What is the bird’s altitude ( y-coordinate) as it flies over x = 0 for the first time after t = 0?
