A spacecraft with I=80 kg\cdotpm2I=80\ \text{kg·m}^2 must reach ω=0.60 rad/s\omega=0.60\ \text{rad/s} from rest; during a short burn, external torques are negligible except for the thrusters, so J=ΔL=IΔωJ=\Delta L=I\Delta\omega. Assume the torque direction matches the desired rotation. Considering the described system, calculate the angular impulse applied to the spacecraft during the interval.
