Explanation / Answer

Momentum = velocity x mass

Velocity = distance / time

meter = 40 * .914 = 36.56 m

So momentum of running back = (distance x mass)/time

= (36.56 x 100)/4.3

=850.36 ...

momentum is 850.36 kg m/s

So momentum for lineman = (distance x mass)/time = (36.56 x 135)/5

=987.12 ...momentum is 987.12 kg m/s

C) The lineman
