Two objects moving along the same straight line are leaving point A with an acceleration a, 2 a & velocity 2 u, u respectively at time t = 0. The distance moved by the object with respect to point A when one object overtakes the other is:
A
B
C
D
none of these
Text Solution
Verified by ExpertsThe correct answer is:
A
Suppose at point B (displacement S) II particle overtakes particle I
For I particle S = (2u) t + 
a t 2 .............
For II particle
S = u t + 
(2a) t 2 ....................
2ut + 
a t 2 = ut + 
(2a) t 2
ut = 
a t 2
t = 
Putting this value in equation we get
S = 2u × 
+ 
× a × 
= 
+ 
=
