Question

3 kg body has a velocity of icap + 6 j cap metre per second and 2 kg body has a velocity of two icap - j cap metre per second then velocity of centre of mass is

Answer 1

Answer:2.08

Explanation:

Vcm,i=(M1V1+M2V2)/M1+M2 here m2v2 is zero as no vector along that direction

I.e 0.6i m/s

Vcm,j =(M1V1+M2V2)/M1+M2

I.E 2j m/s

Resultent =root{(0.6)squar+(2)squar}

Ans 2.08
