A 9mm bullet has a mass of 0.007 kg. When fired from a handgun, its momentum is measured to
be 2.66 kgm/s. What is the velocity of the bullet?

The velocity of the bullet is 380 m/s

Explanation:

The given parameters are;

The mass of the 9 mm bullet fired = 0.007 kg

The measure of the momentum the bullet has = 2.66 kg·m/s

The equation for linear momentum is given as follows;

The linear momentum of an object = The mass of the object × The velocity of the object

∴ The velocity of the object = The linear momentum of an object/(The mass of the object)

The velocity of the bullet = The linear momentum of an bullet/(The mass of the bullet)

The velocity of the bullet = 2.66 kg·m/s/(0.007 kg) = 380 m/s

The velocity of the bullet = 380 m/s.
