3. (25 points) Princess Ricki and her friends are curious as to how some of their favorite toys work. Consider the function h(t) = -16t2 + 150t + 6. This function gives the height of one of their toy rockets t seconds after it is launched. (a) Determine the derivative of h(t) = -16t2 + 150t + 6. (b) Determine any point where the graph of h(t) has a horizontal tangent. How might you interpret this point on the curve? (c) How many seconds is the toy rocket in the air?4.
