If a football player running down the field is tackled by another football player who holds onto the first football player so that they both fly out of bounds together, that collision is ___________.

If a football player running down the field is tackled by another football player who holds onto the first football player so that they both fly out of bounds together, that collision is inelastic.

An inelastic collision can be defined as a type of collision in which the total kinetic energy possessed by the colliding bodies doesn't remain the same as a result of internal friction.

This ultimately implies that, in an inelastic collision the maximum amount of kinetic energy possessed by the colliding bodies isn't conserved (kinetic energy is lost) after the collision, this is due to the action of an internal friction.

Mathematically, inelastic collision is given by the formula;

[tex] V=\frac{(M_{1}V_{1}+M_{2}V_{2})}{(M_{1}+M_{2})}[/tex]

Where;

V is the final velocity in m/s.

M1 is the mass of the first object in kgs.

M2 is the mass of the second object in kgs.

V1 is the initial velocity of the first object in m/s.

V2 is the initial velocity of the second object in m/s.
