Transcribed Image Text:1.(8%) Figure 1 shows two particles moving in a XY
plane. Particle P1 has mass 6.8kg and speed vi 2.3
m/s. It is at distance d1=1.7m from point O. Particle
P2 has mass 3.4kg and speed v2 =3.7m/s It is at
distance d2 =2.9m from point O. Please calculate the
magnitude (a) and direction (b) of the net angular
momentum of the two particles about O.

Transcribed Image Text:5.(15%) Figure 4 shows a uniform beam of weight
450.0N and length 3.0m is suspended horizontally
by a hinge and a cable. If the least tension that will
snap the cable is 1250.0N, please find:
(a) the value of D corresponds to that tension;
(b) the value of D should be decreased or increased
to prevent the cable from snapping.
