MHT CET 2023 Physics question
A mass 'M' moving with velocity 'V' along x-axis collides and sticks to another mass 2M which is moving along Y-axis with velocity '3V'. The velocity of the combination after collision is
Answer: (A)
Solution
No external force acts, so total linear momentum is conserved (perfectly inelastic collision). Initial momentum . After sticking, the combined mass is with velocity : \vec{v}\hat{i}$
