A bullet leaves a rifle with a muzzle velocity of 521 m/s. While accelerating through the barrel of the rifle, the bullet moves a distance of 0.840 m. Determine the acceleration of the bullet (uniform acceleration)

V^2 = 2ad = (521)^2,
2a*0.84 = 271441,
168a = 271441,
a = 271441 / 1.68 = 161572 m/s^2.
