To find the relative velocity of object B from the perspective of object A, subtract the velocity of object A from the velocity of object B.

Velocity of object A: ( \frac{(-4, -4) - (0, 0)}{4} = (-1, -1) ) m/s

Velocity of object B: ( \frac{(2, -6) - (0, 0)}{4} = (0.5, -1.5) ) m/s

Relative velocity of B from the perspective of A: ( (0.5, -1.5) - (-1, -1) = (1.5, -0.5) ) m/s

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- A projectile is shot from the ground at an angle of #pi/8 # and a speed of #4 m/s#. When the projectile is at its maximum height, what will its distance from the starting point be?
- Objects A and B are at the origin. If object A moves to #(3 ,-4 )# and object B moves to #(2 ,7 )# over #8 s#, what is the relative velocity of object B from the perspective of object A? Assume that all units are denominated in meters.
