Do you know the mass of the car?
downward force then reaction if you mean what forces
The mass of the football player is 250 kg.
<u>Explanation:</u>
Momentum is defined as the product of mass and velocity. So here the velocity (v) is given as 10 m/s and the momentum is given as 2500 kg m /s. So we can determine the mass (m) of the player by substituting the known terms in the formula of determining momentum as shown below.

As we know the value of momentum and velocity, the mass can be found as,

Thus, the mass of the football player is found to be 250 kg.
