During a construction project, a hammer is accidently dropped from a height of 400 feet. The distance (in feet) the hammer falls in t seconds is 16t^2. With this information, it's height (in feet) off the ground at time t (in sconds) can be measured by h(t) = 400 - 16t^2. A physicist is interested in the time it takes the hammer to hit the ground (where height is 0 feet). The answer is ... Ot 16 seconds O t = 25 seconds t=200 seconds Ot=5 seconds
