Question 1011375
A helicopter is moving up at a constant speed of 2.35 m/s when it drops a box of supplies for troops waiting below. How fast is the box falling 1.50 seconds after it is dropped? How far below is the helicopter 1.50 seconds after the box is dropped?
--------------------
Using 5 m/sec/sec for Earth's gravitational acceleration:
---
How fast is the box falling 1.50 seconds after it is dropped?
v = at = 5*1.5 = 7.5 m/sec
------
How far below is the helicopter 1.50 seconds after the box is dropped?
s = at^2/2 = 5*1.5^2/2 = 5.625 meters
