Two friends are watching a bird flying above them and recording its location in time. The first finds that Rb1=(2t^2)i + (5t) +(20)k and the second finds that Rb2=(6t-2t^2)i-(t)j+(20)k.
a) Find the location of the second friend relative to the first?
b) Find the velocity and speed of the bird at t=5 second relative to each of the two friends (give each relative velocity)?
c) Find the velocity of the second friend relative to the first?
d) Find the acceleration of the bird relative to each of the two friends?
