Statement of a problem № 41610


The coordinates of a bird flying in the xy-plane are given by X (f) = at and y (l) = 3.0m - /312, where a = 2.4m/s and J3 = 1.2 m/s2 (a) Sketch the path of the bird between t = 0 and I = 2.0 s. (b) Calculate the velocity and acceleration vectors of the bird as functions of time. (c) Calculate the magnitude and direction of the bird s velocity and acceleration at I = 2.0 s. (d) Sketch the velocity and acceleration vectors at I = 2.0 s. At this instant, is the bird speeding up, is it slowing down, or is its speed instantaneously not changing? Is the bird timing? If so in what direction?
