While riding in a hot air balloon, which is steadily descending at a speed of 1.39 m/s, you accidentally drop your cell phone.

(a) After 4.00 s, what is the speed of the cell phone?

(b) How far is the cell phone below the balloon after this time?
d = m

(c) What are your answers to parts (a) and (b) if the balloon is rising steadily at 1.39 m/s?
v =

The analysis is the same as in parts (a) and (b), only now the balloon is moving upward. How will that affect the distance between the balloon and phone at the later time? m/s
d = m
