A bullet comes out of the barrel of gun of length 2 m with a speed 80 ~m / s . The average acceleration of the bullet is

Options

  1. A1.6 ~m / s ^2
  2. B160 ~m / s ^2
  3. C1600 ~m / s ^2
  4. D16 ~m / s ^2

Correct answer

C. 1600 ~m / s ^2

Step-by-step solution

Given, s=2 ~m , u=80 ~m / s , v=0 From v^2=u^2-2 a s (0)^2=(80)^2-2 a 2 or a= 80 80 4 =1600 ~m / s ^2
