Newton's Second Law

Then the Second Law is:
The net external force F acting on a material object is related to the mass m of the object and its acceleration a by

F = ma
or
a = F/m

A force of 1 Newton applied to a body with a mass of 1 kilogram produces an acceleration of 1 meter/second.
How much acceleration do you get if you apply a force of 3 N to a 1 kg body?
How much acceleration do you get if you apply a force of 1 N to a 3 kg body?
