(a)

Just before ‘ ’ collides with ‘ ’, the velocities of all particles will be same and along -axis. Let it be  At this time let velocity of ‘ ’ be along -axis, and that of ‘ ’’ be  along -axis

From conservation of momentum along -axis,

 A car of length 3 m moves at a constant velocity 36 km/hr. A man wants to take a photo of side view of the car. The size of the image of the car is 1.5 cm long. The time of exposure  needed for the car to get a clear picture, if the image should not move more than 0.1 mm, is: (a) 1.5 x 10-3 s (b) 3 x 10-3 s (c) 2.8 x 10-3 s (d) 2 x 10-3 s
