Relatively speaking, the thickness of earth's atmosphere is incredibly small compared to earth's radius (rearth decline in the abundance of air molecules as you move further away from the planet's surface. =6.37-10° m). consider that there is no physical boundary between earth and space, but instead a slow (a) using the information in table c.5 (smits), determine an empirical relation between air density and altitude up to 80 km. you may use either excel or matlab to import the data. fit the data with an exponential best fit curve that forces the intercept through the 0 value of p(0)-1.225. provide a fitted equation (accurate to 3 significant figures). note this equation is not y(z), but instead p(z) and the plot plot of the data with the should reflect this. (b) considering the volume of a thin spherical shell, estimate the total mass of earth's atmosphere.

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
