A110 kg football lineman is running to the right at 2.75 m/s while another 125 kg lineman is running to the left directly toward the first lineman at 2.6 m/s. a) what is the magnitude and direction of the net momentum of the two linemen? b) what is the total kinetic energy of the two linemen?

To solve this problem it is necessary to apply the equations concerning the moment and the total calculation of this.

The momentum can be defined as,

L = vm

Where,

m = mass

v = Velocity,

PART A) For this specific case we have two momentum that would be defined as

PART B) Kinetic energy can be defined as

Where,

m= mass

v= velocity

The total kinetic energy would be,

i think the answer would be reserve.
