a ballistic pendulum an object of mass m is fired with an initial speed to at a ndulum bob. The bob has a mass M, which is suspended by a rod of length L and gligible mass. After the collision, the pendulum and object stick together and swing a maximum angular displacement 0 as shown (Figure 1). Constants Per Part A Find an expression for to. the initial speed of the fired object Express your answer in terms of some or all of the variables m, M, L, and e and the acceleration due to gravity, g >View Available Hint(s) Vo AE Submit Part B An experiment is done to compare the initial speed of bullets fired from different handguns a 9.0 mm and a 44 caliber. The guns are fired into a 10-kg pendulum bob of length L. Assume that the 9.0-mm bullet has a mass of 60g and the 44-caliber bullet has a mass of 12 g. If the 9.0-mm bullet causes the pendulum to swing to a maximum angular diplacement of 43" and the 44caliber bulet causes a displacement of 10.1", find the ratio of the initial speed of the 9.0-mm bullet to the speed of the 44-caliber bulet.
