A particle is acted on by two torques about the origin: τ₁ has a magnitude of 3.0 Nm and is directed in the positive direction of the x-axis, and τ₂ has a magnitude of 5.0 Nm and is directed in the negative direction of the y-axis. In unit-vector notation, find ΔL/Δt, where ΔL is the angular momentum of the particle about the origin.
