Abullet emerges from the muzzle of a gun with a velocity of 300m/s. The net force on the bullet, while it is in the gun barrel, is given by: F(t): =400N-(1.33*10^5N/S)t and is directed along the length of the barrel.
a) Construct the graph of F versus t.
b) Compute the time required for the bullet to travel the length of the barrel, assuming the force becomes zero just at the end of the barrel.
c) Find the impulse of the force as the bullet travels the length of the barrel.
d) Find the mass of the bullet.
