A cannon sits on the ground and fires a cannonball onto a cliff with a height of 51.54 m (picture below). The cannonball leaves the cannon at 58.52 m/s at an angle of 74.26 degrees, which then lands on level ground on top of the cliff. How far in the x direction does the cannonball travel

In 1995 a research group led by eric cornell and carl wiemann at the university of colorado successfully cooled rubidium atoms to the 20-200 nk temperature range. assuming (incorrectly) that the rubidium atoms behave liké particles of a classical ideal gas, calculate the rms speed of a rubidium atom at a temperature of 112.0 nk. in the experiments one particular isotope of rubidium was used, rubidium-87. the molar mass of this isotope is 86.91 q/mol. tries 0/20 submit answer
