An airplane is flying horizontally with a constant velocity of 160 m/s at an altitude of 5100 m when it releases a package.
a. How long does it take for the package to reach the ground? (Ignore air resistance.)
b. What is the distance between the airplane and the package when the package hits the ground? Ignore air resistance.
c. How far ahead of the target along the x direction should the plane be when it releases the package? (Again, ignore air resistance.)

Physics 
bobpursley,
a. h=sqrt(1/2 g t^2_
solve for t.
b. distance=time*160m/s that is horizonal distance. Slant distance is
slant distance=sqrt(5100^2+horizontalDistanc^2)
c.what was horizontal distance in b?
