If a 1kg object is moving at 3m/s in a positive direction, and a 12N force is applied in the negative direction, what is the velocity immediately after 2s? I'm fairly sure this will be a variation of relevent momentum equations, and/or mixed with kinematics, yet I'm not seeing the correct application. I lean towards answers c or b. Obviously mo will be conserved. conservation of mo: m1Vi= (m1+m2)vf t=v/a a. 12m/s b. 6 m/s c. 3 m/s d. 0 m/s Please explain.
