Question

2mass bodies of masses 2kg and 3kg are moving with speed 40m/s and 30m/s rest after this sticks together ,what is velocity both of after calculate

Answer 1

Answer:

The position of COM from 2 kg mass is 3×1/(2+3)=0.6 m

So MI of 2 kg mass about COM is 2×0.6

2

=0.72 kg m

2

and MI of 3 kg mass about COM is 3×0.4

2

=0.48 kg m

2

So total MI is 0.72+0.48=1.2 kg m
