In a movie stunt, a stunt double jumps out of a helicopter without a parachute. She falls to the ground according to the equation h = 2000 - 16t?, in which h is her height above the ground in feet and t is the time
since she has jumped in seconds. On the ground, a semi-truck is holding a large cushioned landing pad,
however it does not start directly under the helicopter. It is driving toward the place directly under the
helicopter at a constant speed of 50 mph and is exactly 820 feet away from that spot when she jumps. When
will the stunt double get to the ground and will the semi-truck with its cushion be there in time to save her?
