While laying on the South Oval grass on a beautiful spring day, you notice two African swallows flying toward each other, both of them carrying coconuts. The first swallow is flying north horizontally with a speed of 20 m/s and the other swallow is flying south horizontally at the same height with a speed of 15 m/s. The mass of the first swallow is 0.27 kg and the mass of his coconut is 0.80 kg. The mass of the second...

Introduction: In this lab you will investigate the conservation of linear momentum: momentum before an event equals momentum after an event if there is an absence of a non-conservative forces such as friction. The event is this case is a collision between two air track gliders. Two types of collisions will be studied. One is an elastic collision which will not be studied in this lab. after the collision. The second is an inelastic collision where after two objects collide,...

This problem will review one of the questions in the ideal gas, but with numbers: You have one container of hydrogen, and another container of oxygen. The number of molecules, temperature and volume are the same for both gases. Oxygen is, however, heavier than hydrogen. How does the average kinetic energy of hydrogen compare to oxygen? Hydrogen has LARGER average kinetic energy than oxygen. Hydrogen has THE SAME average kinetic energy as oxygen. Hydrogen has LESS average kinetic energy than...
