A particle moving with kinetic energy K makes a head on elastic collision with an identical particle at rest. Find the maximum elastic potential energy of the system during collision.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
K/2.
Sol.
from momentum conservation
mu + 0 = (m + m) v ⇒ v = 
from energy conservation
P.E. = 
mu 2 – 
2m 
mu 2 = K
P.E. =
