Explanation / Answer

Dear Student Thank you for using Chegg !! Given Initial Height = 2008 feet Height at any time t for the falling object is = -16t^2 + 32t + 2008 Now to compute time when height is 1000 feet 1000 = -16t^2 + 32t + 2008 16t^2 - 32t - 1008 = 0 t^2 - 2t - 63 = 0 t^2 - 9t + 7t - 63 = 0 t ( t - 9) + 7 (t - 9) = 0 (t + 7) ( t- 9 ) = 0 t '= 9, -7 So height is 1000 feet at t= 9 sec
