S From a clifftop over the ocean 100 m above sea level, an object was shot straight up into the air with an initial vertical speed of 245. On its way down it missed the cliff and fell into the ocean. Its height (above sea level) as time passes can be modeled by the quadratic function f, where f(t) = -4.9t² + 245t + 100. Here t represents the number of seconds since the object's release, and f(t) represents the object's height (above sea level) in meters. 1) After 2) This object flew for > this object reached its maximum height of before it landed in the ocean. (Use m for meters, and s for seconds.) 3) This objict was 4) This object was 2986.1 m above sea level twice: once after its release, and again later above sea level 22 s after its release. after its release.
