How many newtons is 3000 pounds?

For an object experiencing a constant net force, Newton's Second Law of Motion can be used to obtain the equation

F = ma,

where F is the net force, m is the mass of the object and a is the acceleration of the object due to the net force, F. Rearranging the equation for acceleration and substituting in the mass of the box and the net force acting on it gives

a = 900N/300kg

a = 3ms-2.
