A car and a truck have the same kinetic energies at a certain instant while they are moving along two parallel roads. Which one will have greater momentum?

A car and a truck have the same kinetic energies at a certain instant

1.	A car and a truck have the same kinetic energies at a certain instant while they are moving along two parallel roads. Which one will have greater momentum?
Answer» Solution :`K=P^2/(2M), P=sqrt(2mK)` `P PROP sqrtm` for the same KE. So TRUCK will have greater momentum.
