What is the length of the barrel

Reference no: EM13284148

The speed of a bullet as it travels down the barrel of a rifle toward the opening is given by v = (-5.30 107) t 2 + (3.15 105) 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 and position of the bullet as a function of time when the bullet is in the barrel. (Use t as necessary and round all numerical coefficients to exactly 3 significant figures.)

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

(d) What is the length of the barrel?
