Two bodies have kinetic energies in the ratio 4:1. What is the ratio of their momenta?
Step 1: Given,
Ratio of kinetic energy K1: K2=4 :1
Step 2: Formula used,
Kinetic energy K and momentum p is related as where m is the mass.
Step 3: Finding the ratio of momenta
We can write as,
Hence, the ratio of the momenta is .
