Two small objects each of mass m = 0.6 kg are connected by a lightweight rod of length d = 0.7 m (see the figure). At a particular instant they have velocities whose magnitudes are v1 = 37 m/s and v2 = 57 m/s and are subjected to external forces whose magnitudes are F1 = 73 N and F2 = 32 N. The distance h = 0.2 m, and the distance w = 0.8 m. The system is moving in outer space. (a) What is the total (linear) momentum P→total of this system? P→total = kg⋅m/s (b) What is the velocity v→cm of the center of mass? v→cm = m/s (c) What is the total angular momentum L→A of the system relative to point A? L→A = kg⋅m2 /s (d) What is the rotational angular momentum L→rot of the system? L→rot = kg⋅m2 /s (e) What is the translational angular momentum L→trans of the system relative to point A? L→trans = kg⋅m2 /s (f) After a short time interval Δt = 0.23 s, what is the total (linear) momentum P→ total of the system? P→total = kg⋅m/s
