Question
A helicopter holding a 70-kilogram package suspended from a rope accelerates upward at a rate of 5.2 m/s2.
(a) Determine the tension in the rope.
(b) If the package had an acceleration of 0 instead, how would the new tension in the rope compare to the gravitational force experienced by the package (i.e. tension would increase, decrease, stay the same). Explain your reasoning.

Total force on m in up direction = T - m g
F = m A
so
T - m g = m A
T = m (g+A)
if a = 0 then T = m g
F = m A
so
T - m g = m A
T = m (g+A)
if a = 0 then T = m g
