Q- Two masses 5 kg and 15 kg are moving along x direction with velocities of 10 m/s and 2 m/s respectively. At an instant they are at positions 10 m and 70 m respectively
(A) Find position of their center of mass at this instant.
(B) If the two will collide inelastically what is their common velocity?
(C) If they collide elastically find the velocity of each one after collision.
