In 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 ^ 2 which h her height above the ground in feet and is the time 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. Wher will the stunt double get to the ground and will the semi-truck with cushion be there in time to save her? Show your work
