Velocity of mail bag released from helicopter

[physicsphreak123]

A small mail bag is released from a helicopter. The helicopter is rising with a constant speed of 1.5 m/s

After 2.0 seconds, what is the VELOCITY of the mailbag?
I use the equation Vf = Vi + a*t
and a would be 9.8 m/s squared right?

 

[mathmike]

yes 9.8 is correct

so what is the vel after 2 sec.

if the helicopter is at a height if 100 m what is the height of the bag after 2 secs

the velocity would be 21.1 m/s and the height of the bag would be 57.8 m ?
