# An Alaskan rescue plane traveling 35 m/s drops a package of emergency rations from?

a height of 142 m to a stranded party of explorers.The acceleration of gravity is 9.8 m/s2.Where does the package strike the ground relative to the point directly below where it was released?Answer in units of m.

Update:

Part 2. What is the horizontal component of the velocity just before it hits? Answer in units in m/s

Part 3.What is the vertical component of the velocity just before it hits?  (Choose upward as the positive vertical direction)Answer in units of m/s

since the initial vertical velocity is zero,

h = ½gt^2

t = √(2h/g) = 5.38 sec

x = v*t = 35m/sec * 5.38sec = 188 m

distance = 1/2 * a * time^2.  find the time.

Distance forward the package moves (neglecting air resistance) = time * horizontal speed.
