A 6.0 kg mass in the xy plane is moving in the negative x direction at 3.0 m/s along the line y = 4.0 m. As the mass passes the point (x, y = 10 m, 4.0 m), what is its angular momentum with respect to the z axis?

The angular momentum L with respect to the z-axis is given by L = m * v * r, where m is the mass, v is the velocity, and r is the perpendicular distance from the line of motion to the axis. Here, m = 6.0 kg, v = 3.0 m/s, and r = 4.0 m (the y-coordinate). Thus, L = 6.0 kg * 3.0 m/s * 4.0 m = 72 kg·m²/s.
