  1. Well, I do not know what
    "d value of l "
    means but
    final momentum south = initial momentum south
    so
    5 * 20 = (5+3) * new v south = momentum before and after
    100 = 8 v
    v = 100/8 m/s south

  2. Given:
    M1 = 5kg, V1 = - 20m/s.
    M2 = 3kg, V2 = 0.
    V3 = Velocity of M1 and M2 after colliding.

    Momentum before = Momentum after.
    M1*V1 + M2*V2 = M1*V3 + M2*V3.
    5 *(- 20) + 3 * 0 = 5V3 + 3V3,
    8V3 = -100,
    V3 = -12.5 m/s = 12.5 m/s, South.
