An 85 kg linebacker is running at 8 m/s directly toward the sideline of a football field. he tackles a 75 kg running back moving at 9 m/s straight toward the goal line (perpendicular to the original direction of the linebacker.) as a result of the collision both players momentarily leave the ground. determine their common speed and direction immediately after they collide.
i know the answer is 6.0 m/s and 45 degrees toward the sidelines from the running backs' original path. i don't understand how to do this problem. show all work and how to get this answer.

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.

The air in an automobile tire with a volume of 2.60 ft3 is at 70°f and 21 psig. determine the amount of air that must be added to raise the pressure to the recommended value of 30 psig. assume the atmospheric pressure to be 14.6 psia and the temperature and the volume to remain constant. the gas constant of air is ru = 53.34ft⋅lbflbm⋅r(1 psia144 lbf/ft2) = 0.3704 psia⋅ft3lbm⋅r the amount of air that must be added to raise the pressure is lbm
