How do you calculate air resistance on an object if you have how much the object weighs and the acceleration?

Answer 1

Is the object falling at constant terminal speed?

Air Resistance then equals weight.

Answer 2

if it is falling
m g down positive
F air resistance up
a down positive

Weight - Fair resistance = m a

m a = m g - Fair resistance

if the F air resistance were equal to the weight, mg , then the acceleration would be zero

m (g-a)

Answer 3

Well the question never mentioned it if it was at a constant speed, the weight of the object is 1.42N and the acceleration is 4.9m/s^2

how would I calculate that?
