A metal ball of mass 2 kg moving with a velocity of 36 km/h has a head on collision with a stationary ball of mass 3 kg. If after the collision, the two balls move together, the loss in kinetic energy due to collision is [1997]
  • a)
    140 J
  • b)
    100 J
  • c)
    60 J
  • d)
    40 J

Applying conservation of momen tum, 
Here, v1 = 36 km/hr = 10 m/s m1 = 2 kg, m2 = 3 kg
K.E. (initial) =
K.E. (Final) =
Loss in K.E. = 100 – 40 = 60 J
