MCQ
When the speed of a moving body is doubled
  • A
    Its acceleration is doubled
  • Its momentum is doubled
  • C
    Its kinetic energy is doubled
  • D
    Its potential energy is doubled

Answer

Correct option: B.
Its momentum is doubled
b
(b) Its momentum gets doubled. momentum is mass times speed $p=m v$

Therefore when speed is doubled, momentum $'p'$ gets doubled. $p^{\prime}=2 p$
