A car has the same kinetic energy when travelling north as when it turns around and travels south. Is the momentum of car same in both cases?

Step 1

Let, Kinetic energy = E

Kinetic energy in north = kinetic energy in south = E

Step 2

Relation between the kinetic energy and the momentum can be given as

Step 3

From equation (1...
