Lily AdamsAcceleration is the rate of change of speed with respect to time. In other words, acceleration measures how quickly the velocity of an object is changing. If an object's acceleration is positive, its speed is increasing. If acceleration is negative, its speed is decreasing. If acceleration is zero, the speed is constant.

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 is at rest at #(4 ,1 ,2 )# and constantly accelerates at a rate of #7/5 m/s^2# as it moves to point B. If point B is at #(5 ,6 ,1 )#, how long will it take for the object to reach point B? Assume that all coordinates are in meters.
- A projectile is shot from the ground at a velocity of #5 m/s# and at an angle of #(2pi)/3#. How long will it take for the projectile to land?
- Two of the tires on a tractor-trailer have 1.5 m diameters. If the tractor-trailer travels at a linear velocity of 3.0 m/s, what is the angular velocity of each tire?
- An object is thrown vertically at a height of #14 m# at #1 m/s#. How long will it take for the object to hit the ground?
- An object has a mass of #6 kg#. The object's kinetic energy uniformly changes from #42 KJ# to # 15 KJ# over #t in [0, 8 s]#. What is the average speed of the object?
