Ballistics experts are able to identify the weapon that fired a certain bullet by studying the markings on the bullet. Tests are conducted by firing into a bale of paper. If the distance s, in inches, that the bullet travels into the paper is given bys = 27 − (3 − 10t)3for 0 ≤ t ≤ 0.3 second, where t is the time in seconds after the bullet hits the paper, find the velocity of the bullet one-tenth of a second after it hits the paper.
