ANSWER

J=Δp=m(v−u)J = \Delta p = m(v-u). Impulse equals change in momentum, which is mass times velocity change.

Two carts collide on a low-friction track. Cart 1 has mass m1=1.5 kgm_1 = 1.5\,\text{kg} and initial velocity v1i=+8.0 m/sv_{1 i} = +8.0\,\text{m/s} (right). Cart 2 has mass m2=3.0 kgm_2 = 3.0\,\text{kg} and is initially at rest (v2i=0v_{2 i} = 0). After an inelastic collision (they bounce apart), Cart 1 moves left at v1f=−2.0 m/sv_{1 f} = -2.0\,\text{m/s}. Taking rightward as positive, what is Cart 2's final velocity v2fv_{2 f} (in m/s)?
