Question

here is the question: at a certain time,particle is moving in the +x direction with magnitude of momentum 12.0kgm/s.during the next 0.120s, a constant force f<7.30,-4.50,1.20>N acts on the particle.
(a) what is the magnitude of the momentum of the particle at the end of the 0.120s interval?
(b)if the mas of the particle is 0.80kg,what is its displacement in the 0.120s interval?
