Question

a bullet leaves a rifle with a muzzle velocity of 1024 m/s. while accelerating through the barrel of the rifle the bullet moves a distance of 1680m. determine the acceleration of the bullet (assume a uniform acceleration)

Answer 1

[tex] v^{2} - u^{2} =2as \\ u = 0 \ m/s \\ v = 1024 \ m/s \\ s=1680 \ m \\ (1024)^{2} - (0)^{2} = 2 \times a \times 1680 \\ a = \frac{1024 \times 1024}{2 \times 1680} = \frac{32768}{105} \\ a=312.08 \ m/ s^{2} [/tex]
