In ancient times, catapults were used to fling massive projectiles shattering enemy defenses. A catapult with an arm length of 5.00m initially inclined 6.791 degrees from the horizontal. After firing the projectile, the catapult arm inclined by 45 degrees from the horizontal to project maximum distance. It took 1.3 seconds for the arm to rotate from the initial position to the final position. 1.) What is the angular acceleration? Express it in radians 2.) Determine the projectile's ultimate angular velocity shortly before it took flight. 3.) Calculate the tangential acceleration that the bullet received shortly before it began flight.
