A constant force of 4.0 N to the right acts on a 3.0 kg mass for 0.45 s.

a)Find the final velocity of the mass if it is initially at rest.

b)Find the final velocity of the mass if it is initially moving along the x-axis with a velocity of 12 m/s to the left.

2. Relevant equations

F=p/t

3. The attempt at a solution

okay so for the a i got 0.6 using vf=Ft/m and just plugged in. but for b i don't know what to do..need your help thanks!
