Question

a package is released from a helicopter flying horizontally at a constant soeed of 40m/s. the oackage takes 3.0s to reacg the ground. the effects of air resistance can be ignored. what are the horizontal and vertical speeds of the package just before it hits the ground?

Answer 1

There is no force to change the horizontal component of velocity. u = 40, like period. If the helicopter continues at the same speed and heading, the package will hit exactly beneath it. When you drop a bomb, turn :)

It falls for 3 seconds
v = g t = 9.81 * 3 meters/second

Answer 2

31

Answer 3

horizontal velocity (m/s) vertical velocity (m/s)
A 0 30
B 30 30
C 30 40
D 40 30
E 40 40

CHOOSE.
