Dear Student,
                       
                 Change in velocity =Area under F-t curve mass of particle =12×(10+4)×10×10-370×10-3=100cm/s As  force is acting in opposite direction so acceleration also  is in opposite direction  so  -∆v=vf-vi=vf-50-100+50=vfor vf=50cm/s in reverse direction 
Regard
