Question

Three particles of masses 1 kg, 2 kg and 3 kg are subjected to forces (3i-2j+ 2k)N, (-i+ 2j-k)N, and
(i+j+k)N respectively. The magnitude of the acceleration of the CM of the system is :​

Answer 1

Answer:

a com=(m1a1+m2a2+m3a3) /(m1+m2+m3)

a com=4i+5j+3k/6

magnitde of acom=root50/6=5root2/6

Answer 2

$\sqrt{ \frac{14}{6 } }$
