Two small objects each of mass m = 0.3 kg are connected by a lightweight rod of length d = 1.2 m (see the figure).
Two small objects each of mass m = 0.3 kg are connected by a lightweight rod of length d = 1.2 m (see the figure). At a particular instant they have velocities whose magnitudes are v1 = 39 m/s and v2 = 53 m/s and are subjected to external forces whose magnitudes are F1 = 75 N and F2 = 35 N. The distance h = 0.3 m, and the distance w = 0.7 m. The system is moving in outer space.(image: http://www.webassign.net/mi3/11-079-forces_on_barbell.jpg)(a) linear momentum ptotal of the system: <27.6,0,0>kg·m/s(b) velocity vcm of the center of mass: <46,0,0>m/s(c) What is the total angular momentum LA of the system relative to point A?LA = _____ kg·m^2/s(d) What is the rotational angular momentum Lrot of the system?Lrot = _____ kg·m^2/s(e) What is the translational angular momentum Ltrans of the system relative to point A?Ltrans = _____ kg·m2/s(f) After a short time interval t = 0.18 s, what is the total (linear) momentum ptotal of the system?ptotal = <34.8,0,0> kg·m/sAll the answers have to be in vector forms.
