Question

Match the following, if a body has intial and final kinetic energies as K.E1 and K.E2 respectively.
  1. v2 =2v1
  2. v2 =3v1
  3. v2 =4v1


Solution

The correct option is
Kinetic energy =12mv2, where m is the mass of the object, v is the velocity of the object.
Given,
Intial kinetic energy K.E112mv21.
Case - I
When v2 = 2v1
K.E212mv22
12m(2v1)2
K.E2 = 2K.E1
Case-II
When v2 = 3v1K.E2 = 9K.E1
Case-III
When v2 = 4v1K.E2 = 16K.E1
