if a missile is fired from a tank it gets a momentum of 2000 kg metre per second if the velocity of the Missile 50 metre per second what will be its mass

40kg

Explanation:

Given parameters:

Momentum of the missile  = 2000kgm/s

Velocity of the missile  = 50m/s

Unknown:

Mass of the missile  = ?

Solution:

Momentum of a body is the amount of motion a body posses. It is mathematically defined as the product of mass and velocity;

     Momentum  = mass x velocity

The unknown is mass, insert the given parameters and solve for it;

     2000 = mass x 50

       mass =   = 40kg
