2. A steel bullet (66.45 g), shot in the horizontal direction, is caught by a stationary pendulum (265.05 g). The pendulum rises 12.55 cm in the vertical direction. Calculate the momentum of the ball-pendulum system at the moment the ball is caught by the pendulum. (7 points)

Abeverage can is made of 3004-h19 aluminum alloy (elastic modulus 69 gpa, tensile yield strength 285 mpa, density 2.72 g/cm^3). the dimensions on the can are approximated as a thin-walled cylinder with a height of 4.83 inches, diameter of 2.60 inches. empty the can has a mass of 14.2 g. determine: a. the wall thickness of the cylinder b. assuming a pinned-pinned condition what is the critical load? c. assuming a fixed-fixed condition what is the critical load?
