A particle of mass m is projected with a speed u from the ground at an angle θ = π /3 w.r.t. horizontal (x-axis). When it has reached its maximum height, it collides completely inelastically with another particle of the same mass and velocity 
. The horizontal distance covered by the combined mass before reaching the ground is :
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
p i = p f
mu + mucos θ = 2mv
⇒ 
so horizontal range after collision = vt
= 
= 
=
