what if he tackles another player with a mass of 100 kg and a velocity of 0m/s. what would the initial momentum of the second player be?

momentum = mass x velocity
p = 150 kg * 5 m/s
p = 750 kg m /s

The movement of an object. Body mass x velocity = momentum.

ρ (RHO) = m * v
Momentum lets you know how dangerouse something is:
a fly at 50m/s . . . . . . ρ = .0001 Kg * 50 = .005 Kgms = Non Lethal
a train at 50 m/s . . . . ρ = 50000Kg * 50 = 2500000 Kgms = Lethal
so a football player at 5 m/s ρ = ....

750kg x m/s/s or 750N
P=mv
P= 150x5
P=750
