1. The problem statement, all variables and given/known data The instruments attached to a weather balloon in the figure below have a mass(m) of 4.8 kg. The balloon is released and exerts an upward force(F) of 109 N on the instruments. What is the acceleration of the balloon and instruments? 2. Relevant equations F = ma 3. The attempt at a solution F = ma 109N = (4.8 kg)(a) a = 109N / 4.8kg a = 22.7 m/s^2 I got this answer, but its not the right answer.
