  If an object is thrown vertically upward with an initial velocity of v, from an original position of s, the height h at any time t is given by: h=-16t^2+vt+s(where h and s are in ft, t is in seconds and v is in ft/sec)
  
  A package is thrown downward with an initial velocity of -5 ft/sec from a helicopter at 300 ft. A) what is the height of the package in 2 sec? B) how long does it take to hit the ground?
  Round answer to 2 decimals Enter: blank ft,blank sec.

  A. h = ho - (Vo*t + 16t^2).
  h = 300 - (5*2 + 16*2^2 )= 226 Ft above
  gnd.
  
  B. h = 300 - (5t + 16t^2 = 0.
  300 - 5t -16t^2 = 0.
  -16t^2 - 5t + 300 = 0.
