A) They are the same. B) The running back. C) The lineman
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
