Lamar has been running sprints to prepare for his next football game. He has found that he can maintain his maximum speed for 45 yards. He’s thinking of running in a 5 km race in a few months, but doesn’t know if he can maintain his maximum speed for the entire 5 km. Can you help him determine how far he can?

If a balloon is taken outside on a very cold day, what will occur?

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
