STEM Lessons for College Students

3.7 .. CALC The coordinates of a bird flying in the xy-plane are given by x1t2 = at and y1t2 = 3.0 m – bt2 where a = 2.4 m>s and b = 1.2 m>s2. (a) Sketch the path of the bird between t = 0 and t = 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 t = 2.0 s. (d) Sketch the velocity and acceleration vectors at t = 2.0 s. At this instant is the bird’s speed increasing decreasing or not changing? Is the bird turning? If so in what direction?

I have not created a lesson for this question yet.

Please leave a comment below with specifics about the question, and I will make a detailed lesson on it as soon as possible. (I can usually have something up within a day.)

NEED IMMEDIATE HELP? Get the student solution manual here: University Physics Manual otherwise, I should be able to get a video lesson up within a day or so.
