    Pressure due to molecular velocity problem

    The value of the velocity that is used during momentum calculation is the velocity in the x direction which would be : Vx = 170 m/s * cos (55 degrees) I converted the velocity from centimeters to meters (velocity in centimeters = 170000 cm/s) and the pressure exerted is: P = [...

    Pressure due to molecular velocity problem

    Hey guys, I am having a little problem with a problem I am doing in Physics (thermo chapter). Well, here is the problem: "The mass of the H2 molecule is 3.3e24 g. If 10e23 H2 molecules per second strike 2.0 cm^2 of wall at an angle of 55° with the normal when moving with a speed of 1.7...
