Speed/Dist question

1. The problem statement, all variables and given/known data
Santa arrives at the local mall by helicopter and, as the helicopter steadily descends at 1.0 m/s, he releases a bag of candy to the children waiting below. After 3 seconds:

a. what is the speed of the bag of candy?
b. how far is it below Santa’s helicopter?
c. What are the answers for parts (a) and (b) if Santa’s helicopter is departing, rising steadily at 1.0 m/s?

2. Relevant equations
For a. v=v0+gt

negative velocity and grav due to descend.

3. The attempt at a solution

a. -1 m/s+(-9.8m/s^2)(3s)
-1+(-29.4)
=-30.4 m/s^2

I need some assistance for the next step…
