First you need the quadratic function that represents this particular situation. Using the vertical motion equation, here is the function: h(t) = -16t 2 + 30t + 10.

1) 0.94 seconds: Using the calculator, first find the location of the maximum point. This point is located at (0.94, 24.06). Since we want the time it takes to reach the maximum height, we want the x-coordinate of the vertex.

2) 2.16 seconds Using the calculator, find the location of the x-intercept (zero). This point is located at (2.16, 0).
