What is the percent change from 10m to the surface. Use absolute pressure and assume standard atmospheric conditions. Would the answer change with a different system of units.
The circular top of a can has a radius of .0320m. the pull-tab has an area of 3.8x10^-4 m^2. The absolute pressure of the carbon dioxide in the can is 1.40x10^5Pa. find the force that these gas generates on the top of a can?
The ball is released from position A and drops 0.75m to the incline. If the coefficient of resistitution in the impact is e=0.85, determine the slant range R. See Engineering Mechanics Dynamics meriam and Kraige 7th edition number 3/255 for figure
