If an object with uniform acceleration (or deceleration) has a speed of #2 m/s# at #t=0# and moves a total of 12 m by #t=5#, what was the object's rate of acceleration?

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.

- An object's two dimensional velocity is given by #v(t) = ( t^2 +2 , cospit - t )#. What is the object's rate and direction of acceleration at #t=2 #?
- A projectile is shot from the ground at a velocity of #86 m/s# at an angle of #pi/3#. How long will it take for the projectile to land?
- An object is at rest at #(8 ,5 ,4 )# and constantly accelerates at a rate of #1/4 m/s^2# as it moves to point B. If point B is at #(2 ,4 ,5 )#, how long will it take for the object to reach point B? Assume that all coordinates are in meters.
