1D kinematics hot air balloon

Question

A hot air ballon is traveling vertically downward at a constant speed of 7 m/s. When it is 30.1 m above the ground, a small package is released from the balloon. What is the package’s velocity just before hitting the ground?

Answer 1

The initial velocity of small package is 7 m/s and downward. V₀ = 7 m/s

V² - V₀² = 2*g*(30.1) → V = sqrt [ 2*9.8*30.1 + (7²)] = 25.3 m/s
