If an apple is dropped from an air balloon at 1350 m, (a) what velocity does the apple strike the earth? (b) how long does it take the apple to fall?
-------------
Using 9.8 m/sec/sec for gravity and neglecting air resistance:
---
s = at^2/2
1350 = 4.9t^2
t+=+sqrt%281350%2F4.9%29 seconds
------------------------
v = at = 9.8*t meters/second
