A bullet with a mass of m = 15g is shot out of a rifle that has a length L = 0.98m The bullet spends t = 0.16s in the barrel.
A.) Write an expression in terms of the given quantities, for the magnitude of the bullet's acceleration, a, as it travels through the rifle's barrel. You may assume the acceleration is constant throughout the motion.
B.) Calculate the numerical value for the magnitude of the bullet's acceleration, a in m/s^2
C.) What is the numerical value of the net force Fnet in newtons acting on the bullet?
