In Exercises 105 and 106, use the position function s ( t ) = − 16 t 2 + 500 , which gives the height (in feet) of an object that has fallen for t seconds from a height of 500 feet. The velocity at time t = a seconds is given by lim t → a s ( a ) − s ( t ) a − t ⋅ A construction worker drops a full paint can from a height of 500 feet. How fast will the paint can be falling after 2 seconds?
