Question 3

Particles C C\,C and DDD, of masses 2 kg and 3 kg respectively, move along the same straight line. Immediately before a direct collision their velocities are (4i+3j) m s−1(4\mathbf i+3\mathbf j)\text{ m s}^{-1}(4i+3j) m s−1 and (8i+6j) m s−1(8\mathbf i+6\mathbf j)\text{ m s}^{-1}(8i+6j) m s−1 respectively. They coalesce on impact.

a.
