Question

The momentum of an object of mass 4 kg with velocity 100 cms-1 is

Answer 1

Answer:

velocity = 100 cm s^-1 = 1 m s^-1

So,

momentum of the object = mass * velocity = 4 kg m s^-1

Answer 2

Answer:

$4kg-m/s$ is the momentum of an object.

Explanation:

• Given,

Mass of an object $= m = 4kg$

Velocity of an object $= v = 100 cm /s$

                                         $= 1m/s$                         $(1 cm/s = 1m/s)$

• To find,

momentum of an object $= ?$

Momentum is the product of the mass of a body and its velocity. Momentum is a vector quantity means it has both magnitude and direction.

• $P = m*v$    where

$P =$ momentum of the body.

$m =$ is the mass of the body.

$v =$ is the  velocity of the body.

• Subsituting the values of mass and velocity in above equation,

        we get,

         $P = 4kg*1m/s$

      $P = 4kg-m/s$

Therefore, the momentum of an object is $4kg-m/s$.
