Certain rifles can fire a bullet with a speed of 950 m/s just as it leaves the muzzle (this speed is called the muzzle velocity). The muzzle is 67.0cm long and the bullet is accelerated uniformly from rest within it.
A.) What is the acceleration of the bullet within the rifle?
B.) For how long is it in the muzzle?
C.) The rifle is fired horizontally from a height of 1.50 m. How long does it take before it hits the ground?
D.) How far from a point on the ground from the end of the muzzle does the bullet travel?
