Momentum of an object = (its mass) x (its speed) .

Since speed is a factor of momentum, an object that
isn't moving doesn't have any.

-- The moving player has momentum. 

-- The stationary one doesn't.

Momentum = Mass * velocity

For the stationary football player, his velocity = 0

Momentum = 75 kg * 0 = 0 kgm/s

The second player =  70kg * 6 m/s = 420 kgm/s

The first player has no momentum, the second player has a momentum of 420 kgm/s
