A Toyota Jeep with mass 1.8x10 kg is travelling eastbound at 15m/s, while a Benz Jeep with mass 9x10'kg is travelling westbound at -15m/s. These cars collide head on and become
entangled. Calculate the velocity of the entangled jeeps after collision, the change in velocity
of each jeep and the change in kinetic energy of the system consisting of both Jeeps.

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?
