The velocity of a 1.2 kg particle is given by ( v = 1.5t³(2.4 - 3t²) ) m/s. Determine the linear momentum of the particle and its magnitude, and the net force ( F ) which acts on the particle at time ( t = 2 s ).
a) Linear momentum = 0, Net force = 0
b) Linear momentum = 0, Net force = 7.2 N
c) Linear momentum = -7.2 kg m/s, Net force = 7.2 N
d) Linear momentum = 7.2 kg m/s, Net force = 0 N
