• 1. In winter with heavy snowfall, animals in Yellowstone cannot roam freely to find food, so hay is dropped for them from helicopters. A helicopter 180 feet above the ground drops a bale of hay while the helicopter itself rises at 32 feet per second. The height (S) in feet of the bale as a function of time is given by:
  S(t)=-16t^2+ vi t + Si
  where t is the time since the bale was released from the helicopters (in seconds) , Vi is the initial velocity,and Si is the initial height.
  'a What is the height of the bale 2 seconds after releasing it?
  b. How many seconds will it take for the bale to reach the ground?
  C. When does the bale reach its maximum height? What is the minimum height?
