Two metal disks, one with radius r1 = 2.45 cm and mass m1 = 0.900 kg and the other with radius r2 = 5.00 cm and mass m2 = 1.60 kg, are welded together and mounted on a frictionless axis through their common center. a light string is wrapped around the edge of the smaller disk and a 1.60 kg block is suspended from the free end of the string. (a) what is the magnitude of the downward acceleration of the block after it is released? (b) repeat the calculation of part (a), this time with the string wrapped around the edge of the larger disk.

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
