A particle of mass m moving in the x direction with speed 2v is hit by another particle of mass 2m moving in the y direction with speed v. If the collision is perfectly inelastic, the percentage loss in the energy during the collision is close to :
Text Solution
Verified by ExpertsThe correct answer is:
C
Just before collision Just after collision
2V 
Energy loss Δ E = 
m (2V) 2 + 
(2m) V 2 – 
(3m) 2 
= 3mV 2 – 
= 
= 55.55%
