Texts: A bullet is shot upwards with an initial velocity of 100 ft/sec from a point 5 ft above the ground, and its height above the ground at time t is given by h(t) = -20t² + 100t + 5.
Added by Austin T.
Step 1
To find the time it takes for the bullet to reach its maximum height, we need to find the vertex of the quadratic equation h(t) = -20t² + 100t + 5. The vertex of a quadratic equation in the form h(t) = at² + bt + c is given by the formula t = -b/2a. In this Show more…
