A particle of mass 
is projected with a speed 
from the ground at an angle 
w.r.t. horizontal ( 
-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
Using principal of conservation of linear momentum for horizontal motion, we have
For vertical motion
Let 
is the horizontal distance travelled by the body.
(For horizontal motion)
