Let u = initial velocity of the first particle

V1, V2 ard the velocities of first  and second particle respectively

θ1 & θ2 are tbe angles made by the first &  second particle respectively with the original direction of  U

Let u = initial velocity of the first particle

V1, V2 ard the velocities of first  and second particle respectively

 

Equting conservation of momentum in the direction of initial direction of U, &  perpendicular to it, one get,

mU + 0  = m V1 cos θ1+ m cosθ2............. i

0 + 0  =   m V1 sinθ1 +  m V2 sinθ2.............ii

 

For elastic collision kinetic energy is also conserved. 

Equating i initial &  final kinetic energener, 

(1/2)mu2  + 0  = (1/2) mV12  + (1/2) m V22 .. Iii

 

&  adding eqn. i,   ii,  

we get 

U2  = V12    +   V22   + 2 V1 V2  cos  (  θ1  +    θ2   ) 

This equation will  be identical to eqn. iii,  only when  (   θ1   +  θ2    )  = 90 degree.

Sameer went on his bike from Delhi to Gurgaon at a speed of 60km/hr and came back at a speed of 40km/hr. What is his average speed for entire journey?
To find the average speed, you need to know the formula of average speed. The avg speed 0= 2 d / (t1+ t2) = 2 v1.v2/(V1 + V2). Just substitute the value.
