A body whose momentum is constant must have constant

Options

  1. Aacceleration
  2. Bforce
  3. Cvelocity
  4. Dmass

Correct answer

C. velocity

Step-by-step solution

Momentum of a moving body with velocity v is given as p=m v Since mass m of a body remains always constant. Hence, if momentum of body is constant, then its velocity must be constant.
