Question

1
6. Two particles of masses 1 kg and 3 kg are moving with
velocity (2 i + 3 j) and (3 i - 4 j) m/s respectively.
Calculate the velocity of centre of mass.​

Answer 1

Answer:

✓101/✓2

Explanation:

vcm= m1v1+m2v2/m1+m2

=(11 i -9j)/4

take out magnitude

121+81=✓101/✓2

Answer 2

Answer:

v= m1v1+m2v2/m1+m2

=(11 i -9j)/4

I hope it helps you.
