1. Work out the following problems. Show the steps clearly.
A particle is moving in a circle where its position as a function of time is giv
by the expression r = a/cos ati + sin olj, where w is a constant. Show that the
total angular momentum of the particle is constant.
A system of particles consists of three masses m1 = 0.5 kg. m2 = 2 kg and m3=5
kg located at P1(-3, 1.2). P2(0, 1, 2) and P3(-1,3,0), respectively.
Find the position vector of the center of mass of the system.
