The path of the packet seen from the plane will be a free fall in straight verticle line .

The path seen from the ground wil be a parabola . The  actual path can only be defined from a particular frame of reference .

Let velocity if plane=v=initial velocity if of packet .so wrt ground it wiĺl be parabola if v is not zero and it will be free fall wrt plane it is moving with constant velocity v

U=2m/s
T=2s
a=-9.8m/square because it is released downwards 
So using v=u+at 
V=(2)+(2)(-9.8)
V=2-19.6 that is v=17.6 m/s
