A beam of hydrogen molecules (H2) is directed toward awall, at an angle of 50° with thenormal to the wall. Each molecule in the beam has a speed of1.5 km/s and a mass of 3.3 10-24 g. The beam strikes the wall over an areaof 2.0 cm2, at the rate of 1023 molecules persecond. What is the beam's pressure on the wall?
