Question

Calculate the momentum of bullet of mass 0.02Kg moving at 400 m/s.​

Answer 1

Answer:

= 0.02kg x 400m/s

= 8 N/s

Explanation:

Momentum= Mass x Velocity

Answer 2

Answer:

Momentum = 8 kg m/s

Explanation:

$\diamond$ Momentum is defined as the quantity of motion possessed by an object

$\diamond$ It is denoted by the letter p

$\diamond$ Since it is a vector quantity that is, has both direction and magnitude, it is shown as $\vec{p}$

$\diamond$ Mathematically it is defined as the product between mass and velocity of the body

$\huge \text{\boxed{\vec{p} = mv}}$

$\diamond$ Given that,

Mass = 0.02 kg

Velocity = 400 m/s

$\diamond$ Therefore,

Momentum = Mass * Velocity

$\vec{p}$ = mv

$\vec{p}$ = 0.02 * 400

$\vec{p}$ = 2 * 4

$\vec{p}$ = 8 kg m/s
