The projectile will reach its maximum height at the midpoint of its flight when its vertical velocity component becomes zero. Use the kinematic equation: (v_f = v_i + at) and (v_f = 0), solve for (t) to find the time it takes to reach maximum height. Given that (v_i = 28 \sin(\pi/6) , \text{m/s}) and (a = -9.8 , \text{m/s}^2), (t = \frac{-v_i}{a}). Plug in the values to find (t).

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 has a mass of #3 kg#. The object's kinetic energy uniformly changes from #12 KJ# to # 72KJ# over #t in [0,5s]#. What is the average speed of the object?
- What is the speed of an object that travels from #(4,-7,1) # to #(-1,3,-8) # over #6 s#?
- An object is at rest at #(7 ,9 ,4 )# and constantly accelerates at a rate of #7/4 m/s^2# as it moves to point B. If point B is at #(7 ,1 ,6 )#, how long will it take for the object to reach point B? Assume that all coordinates are in meters.
- Work out? -two bodies are placed one meter a part. How much further should they be displaced in order to reduce the gravitational force between them by 1/16------? Thanks
- An object has a mass of #4 kg#. The object's kinetic energy uniformly changes from #16 KJ# to # 96KJ# over #t in [0, 6 s]#. What is the average speed of the object?
