A revolving rifle fires 9 mm bullets such that as they travel down the barrel of the rifle their speed is given by v = (-4.75 x 10^7)t^2 +(2.30 x 10^5)t.
where v is in meters per second and t is in seconds. The acceleration of the bullet just as it leaves the barrel is zero.
(a) Determine the acceleration (in m/s2) and position (in m) of the bullet as a function of time when the bullet is in the barrel. (Use the following as necessary: t. Round all numerical coefficients to at least
three significant figures. Do not include units in your answers. Assume that the position of the bullet at t=0 is zero)
a(t)-
X(t)-

(b) Determine the length of time the bullet is accelerated (in s).

(C) Find the speed at which the bullet leaves the barrel (in m/s).

(d) What is the length of the barrel (in m)
