In the final stages of the landing process, a spaceship decelerates at a constant rate of 5.3 m/s2 heading towards the Earth. A 3kg lamp is hanging straight down, attached to the ceiling of the ship cabin by a chain. What is the tension in the chain?

T-mg = ma
T = m(g-a)

9.81 - 5.3 = 4.51
3*4.51 = 13.5 N
