A6.0-kg object undergoes an acceleration of 2.0 m/s2. (a) what is the magnitude of the resultant force act- ing on it? (b) if this same force is applied to a 4.0-kg object, what acceleration is produced?

a) 12 N

b) 3 m/s²

Explanation:

m = Mass of the object

a = Acceleration of the object

Force

Now, F = 12 N

The resultant force acting on the object is 12 Newtons

The acceleration of the 4 kg object which is experiencing the same force is 3 m/s²

no. dot product   =0 when vecs at right angles
