Providing velocity is constant (say they are both running at 0.5ms-1).

The concept of momentum applies in this problem. The sumo wrestler (assume 165kg) will have more momentum despite moving at the same speed.

Momentum is given as the formula p = mv

Where p is momentum, m is mass and v is velocity.

The momentum of the sumo wrestler is 160 x 0.5 = 80kgms-1

The 70kg man has a momentum of:

70 x 0.5 = 35kgms-1

As you can see, the sumo wrestler has a momentum of 80kgms-1 as opposed to the man with a momentum of 35kgms-1.

The person with the more momentum is therefore harder to tackle and more difficult to bring to a stop.
