Question

a body of mass 500kg and it's velocity is 2000cms^-1 find it's momentum

​

Answer 1

Note :-100cm=1m

so 2000cm/s =20m/s

Answer 2

Answer:

momentum = 10,000Kgm/s

Explanation:

mass = 500Kg

Velocity = 2000cm/s = 20m/s                     [convert into SI unit]

so,

we know that,

momentum = mass × velocity

                  = 500 × 20 Kgm/s

                  = 10,000 Kgm/s
