A body of mass 5kg moves along the x-axis with a velocity 2m/s. A second body of mass 10kg moves along the y-axis with a velocity of √ 3 m/s. They collide at the origin and stick together. If the amount of heat liberated in the collision is 
then find λ ?

P x = 5×2 = 10 ; P = P x 
+ P y 
P y = 10 
= 10 
+ 10 
= (5 + 10) V

m/s.
H = Δ E = E i – E f = 
– 
(m 1 +m 2 ) V 2
=

× 10 × 
– 
× (10+5) (4/3) 2 = 25 –
