A uniform disk with mass 100 kg and radius 1.0 m is spinning like a merry-go-round about a vertical axis through its center and perpendicular to the plane of the disk. It rotates at an initial angular speed of rad/s. A 40 kg mass of putty drops from above and lands on a point 0.50 m from the center from the disk and sticks to the disk. What is the final angular speed of the disk-putty system, in rad/s?

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
