An object of mass 3.0 kg is initially moving at +4.0 m/s. A force acts on the object, causing its velocity to change to -6.0 m/s. What is the change in momentum of the object?
−30 kg m/s-30\text{ kg m/s}−30 kg m/s
−6.0 kg m/s-6.0\text{ kg m/s}−6.0 kg m/s
+6.0 kg m/s+6.0\text{ kg m/s}+6.0 kg m/s
+30 kg m/s+30\text{ kg m/s}+30 kg m/s
