A bullet is fired from a gun at the speed of$280 \mathrm{m} {\mathrm{s}}^{-1}$ in the direction $30°$ above the horizontal. The maximum height attained by the bullet is ($g=9.8 \mathrm{m} {\mathrm{s}}^{-2},$ $\sin 30°=0.5$):

• A

  $3000 \mathrm{m}$
• B

  $2800 \mathrm{m}$
• C

  $2000 \mathrm{m}$
• Correct answer
  D

  $1000 \mathrm{m}$

Hence, the correct answer is option: 'D'.
