6. The function h(t) outputs the height of a toy rocket measured in feet at time t seconds after it was launched. h(t)=-16t2 +128t+2 a. Calculate the height of the rocket at time 2 seconds after launch. b. Calculate the height of the rocket at time 3 seconds after launch. c. Calculate the slope of the line that goes through the two points you found in part a and b. d. What are the units of this slope? e. What does that slope represent? f. How could this be represented on the graph of h(t)?
