Consider a height 170 m above the ground (which itself is 1247 m above sea level). If the temperature at this height is 10 C, what is the ratio of the density of this site compared to standard atmospheric conditions (hint - assume you can use the ideal gas law to calculate the density and then divide this value by the standard density value)? (answer to three decimal places)

A cannon shoots a cannonball from the ground level (ignore the height of the cannon) towards a cliff of height h = 170 m
A cannon shoots a cannonball from the ground level (ignore the height of the cannon) towards a cliff of height h = 170 m. The cannonball is launched with an initial velocity of 110 m/s at an angle of 64° above the horizontal. Neglect air resistance. Assume the cannonball hits the cliff as it descends (on its way down) exactly at the edge, as shown. a. Determine the maximum height above the ground reached by the cannonball.b. What speed will the...

9. Pressure at Mt. Everest If we rearrange the ideal gas law to be in terms of density: pR and also consider the affects of the buoyancy force: apE, we can combine these equations to find the atmospheric pressure as a function of height above the ground. Do so to find the air pressure at an elevation of 8838 meters, close to the peak of Mt. Everest. You can assume that g is constant all the way up and so...
