Two bodies of masses m and 4m. are moving with equal kinetic energies. The ratio of their linear momenta is
For a relation between the linear momenta of the two bodies moving with equal kinetic energies, we use the relation of kinetic energy with momentum. Step 1: Kinetic energy and momentum relation The kinetic energy K.E. is related to the momentum p by, Kinetic energy = p2 / (2m) Now, rearranging in teRead more
For a relation between the linear momenta of the two bodies moving with equal kinetic energies, we use the relation of kinetic energy with momentum.
Step 1: Kinetic energy and momentum relation
The kinetic energy K.E. is related to the momentum p by,
Kinetic energy = p2 / (2m)
Now, rearranging in terms of momentum we get,
p = √(2m × K.E.)
Step 2: Given
For the two bodies
Mass of the first body = m
Mass of the second body = 4m
– Both have the same kinetic energy.
Let the kinetic energy of both bodies be \\( K.E. \\).
Step 3: Calculate the momentum of each body
For the first body:
p₁ = √(2m × K.E.)
For the second body:
p₂ = √(2 × 4m × K.E.) = √(8m × K.E.)
Step 4: Find the ratio of momenta
The ratio of their momenta is:
p₁ : p₂ = √(2m × K.E.) : √(8m × K.E.)
p₁ : p₂ = √2 : √8
p₁ : p₂ = 1 : 2
The ratio of their linear momenta is: 1 : 2
