A beam of hydrogen molecules (H2) is directed toward a wall, at an angle of 49 degree with the normal to the wall. Each molecule in the beam has a speed of 2.3 km/s and a mass of 3.3 x 10-24 gram. The beam strikes the wall over an area of 2.0 cm2, at the rate of 1023 molecules per second. Compute what is the beam pressure on the wall?
