A locomotive is accelerating at 3.03 m/s2. It passes through a 16.8-m-wide crossing in a time of 3.18 s. After the locomotive leaves the crossing, how much time is required until its speed reaches 32.2 m/s?

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?
