Question

Two bodies of masses 8 and 2 kg have equal kinetic energies. Then the ratio of their momentum is ​

Answer 1

Answer:

The relation between kinetic energy and momentum is given by,

k = 1/2 mv² = p²/2m

where p is the momentum of body.

Hence

k1/k2 = m2/m1

since momentum of the two bodies are same.

k1/k2 = m2/m1 =?

Answer 2
