Two masses, each 100 grams, are 30 cm connected by an effectively massless rubber band and thrown in the air. m m Initially, the rubber band is stretched to 30 cm as the masses rotate about their center of mass making 7 revolutions each second. The rubber band then pulls in the masses, contracting to 20 cm. How many revolutions per second do the rotating masses make after this contraction?

At an amusement park there is a ride in which cylindrically shaped chambers spin around a central axis. People sit in seats facing the axis, their backs against the outer wall. At one instant the outer wall moves at a speed of 2.75 m/s, and an 86.0-kg person feels a 253-N force pressing against his back. What is the radius of a chamber?
51. ao Two stars in a binary system orbit around their center of mass. The centers of the two stars are 7.17 × 10" m apart. The larger of the two stars has a mass of 3.70 × 100 kg, and its center is 2.08 × 10" m from the system's center of mass. What is the mass of the smaller star?
4. Sphere A has mass ma = 0.06 kg, velocity magnitude va = 3.0 m/s making an angle = V6 magnitude vc = 25° with the + axis. Sphere B has mass m₂ = 0.04 kg, velocity magnitude 4.0 m/s and moves along the +y axis. Sphere C has mass mc = 0.05 kg, velocity 5.0 m/s and moves along the +x axis. See figure. They are all approaching the origin as they slide on a frictionless surface. The three spheres arrive at the origin at the same time and stick together. (a) What is the final velocity of the combined object? (b) How does the final kinetic energy compare to the kinetic energy before the collision?

The motion of a human body through space can be modeled as the motion of a particle at the bodys center of mass as we will study in Chapter 9. The components of the displacement of an athletes center of mass from the beginning to the end of a certain jump are described by the equations xj = 0 + (11.2 m/s) (cos 18.5)t 0.360 m = 0.840 m + (11.2 m/s)(sin 18.5)t - 12(9.80 m/s2)t2 where t is in seconds and is the time at which the athlete ends the jump. Identify (a) the athletes position and (b) his vector velocity at the takeoff point. (c) How far did he jump?
