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 plane, whose speed in still air is 360 km/h flies directly from London to Rome, at a distance of 1400 km. The bearing of Rome from London is 135 degree and there is wind of 120 km/h blowing from North? Find?(see below)
- An object is thrown vertically from a height of #7 m# at # 3 m/s#. How long will it take for the object to hit the ground?
- An object is at rest at #(2 ,1 ,6 )# and constantly accelerates at a rate of #1/4 m/s^2# as it moves to point B. If point B is at #(6 ,4 ,5 )#, how long will it take for the object to reach point B? Assume that all coordinates are in meters.
- The position of an object moving along a line is given by #p(t) = 7t - cos(( pi )/3t) + 2 #. What is the speed of the object at #t = 8 #?
- What is the speed of an object that travels from #( -1, 7,2) # to #( -3, -1,0 ) # over #2 s#?
