The speed of a bullet as it travels down the barrel of a rifle toward the opening is given by v = (-18 x 10000) t + (8.0 x100) t m/s Where the time, t is in seconds. The acceleration of the bullet just as it leaves the barrel is zero. The time interval over which the bullet is accelerated is The speed of a bullet as it travels down the barrel of a rifle toward the opening is given by v = (-18 x 10000) t + (8.0 x100) t m/s Where the time, t is in seconds.
