6.A bullet is fired from the top of a building that is 20 m high.The height,h(t),of the bulletabove ground at time t,in seconds,can be modeled by the function h(t )=-4.9t2+98t +20.A)Determine the average rate of change (AROC)during the time interval 8st s11.Includethe correct units.12]B)Use the limits formula (definition of derivative)to determine the instantaneous rate ofchange (IROC)of the bullet’s height at time t=10 seconds.Include correct units andinterpret the meaning of your answer.3
