bullet in a gun is accelerated from the firing chamber to the end of the barrel at an average rate of 6.20×105 m/s2 for 8.10×10?4 s . What is its muzzle velocity (that is, its final velocity)?
Step-by-step solution Step 1 of 3 Apply the kinematics equation, Here v is the final velocity, u is the initial velocity, a is the acceleration and t is the time interval during which a body is under acceleration. Step 2 of 3 The muzzle velocity of a bullet is the velocity with which the bullet leaves contact with the barrel of the gun. The muzzle velocity or the final velocity of the bullet is,
