Hi,
Why is F = ma equals to F =mg?
Also what is F = Fa - Ff? It came from this question.
The question is
c) If the box moves at a constant speed of 2m/s-1 when a 50N force is applied, what is the frictional force? (Box is 10kg)
Answer: Constant speed => a = 0
F = ma = 0
F = Fa - Ff (what's this suppose to mean?)
Ff = Fa = 50N
