A police officer at rest at the side of the highway notices a speeder moving at 62 km/ h along a straight level road near an elementary school. When the speeder passes, the officer accelerates at 3.0 m/ s 2 in pursuit. The speeder does not notice until the police officer catches up. b) How far will they move from the position where the officer was at rest?

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?

What is the relationship between wavelength of light and the quantity of energy per photon?

Water flows through a garden hose which is attached to a nozzle. the water flows through hose with a speed of 2.19 m/s and through the nozzle with a speed of 19.8 m/s. calculate the maximum height (in m) to which water could be squirted if it emerges from the nozzle and emerges with the nozzle removed.
