Question

A plane flying horizontally at a speed of 50m/s and at an elevation of 160m drops a package. two seconds later it drops a second package. How far apart will the two packages land on the ground?
a)100m 
b)162m
c)177m
d)283m

i think the answer is a) I got 150m for the first package and 50m for the second package. so the distance b/w them would be 100m.

Each package will take the same time to hit the ground. So the separation on the ground will be whatever it was between the two release points. That is easy to calculate. (V * t) You don't need the mass, and you don't need the time requred to hit the ground.
