A solid disk rotates in the horizontal plane at an angular velocityof 0.067 rad/s with respect to an axis perpendicular to the disk atits center. The moment of inertia of the disk is 0.10 kgImage for A solid disk rotates in the horizontal plane at an angular velocityof 0.067 rad/s with respect to an axis perp m2. From above, sand is dropped straight down onto the rotating disk, so that athin uniform ring of sand is formed at a distance of 0.40 m fromthe axis. The sand in the ring has a mass of 0.50 kg. After all the sand is in place, what is the angular velocity of thedisk?

1point) a skydiver weighing 130 lb (including equipment) falls vertically downward from an altitude of 14,000 ft and opens the parachute after 20 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.85|v|0.85|v| when the parachute is closed and is of magnitude 17|v|17|v| when the parachute is open, where the velocity vv is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. find the speed of the skydiver when the parachute opens. speed is 150.6121788 ft/s find the skydiver's height when the parachute opens. height is 2338.98591 ft find the limiting velocity vlvl after the parachute opens. (think about whether this should be positive or negative.) vl=vl= 7.647 ft/s
