We have ―

  • Momentum, P = 25 kg.m/s
  • Mass, m = 10 kg

We have been asked to calculate its velocity.

[tex]\qquad \implies\boxed{\red{\sf{ P = mv}}}\\[/tex]

  • P denotes momentum
  • m denotes mass
  • v denotes velocity

[tex] \quad \twoheadrightarrow\sf { 25 = 10v} \\ [/tex]

[tex] \quad \twoheadrightarrow\sf { \dfrac{25}{10} = v} \\ [/tex]

[tex]\quad \twoheadrightarrow\boxed{\red{\sf{ 2.5 \; ms^{-1} = v}}}\\[/tex]

Therefore, its velocity is 2.5 m/s.
