Two cars of same mass are moving with same speed v on two different roads inclined at an angle 
with each other, as shown in the figure. At the junction of these roads the two cars collide inelastically and move simultaneously with the same speed. The speed of these cars would be
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Initial horizontal momentum of the system
If after the collision cars move with common velocity V then final horizontal momentum of the system = 2mV.
By the law of conservation of momentum, 2mV
