A spacecraft has moment of inertia I=1200 kg⋅m2I=1200\ \text{kg}\cdot\text{m}^2 about its yaw axis and initially ωi=0\omega_i=0. Its attitude-control thrusters provide a constant torque τ=240 N⋅m\tau=240\ \text{N}\cdot\text{m} for t=3.0 st=3.0\ \text{s}, so angular impulse J=τt=ΔLJ=\tau t=\Delta L. Based on the scenario above, calculate the angular impulse applied to the spacecraft during the interval.
