Asolid spherical ball starts from rest at height h at the top of a hill and begins rolling without slipping down the hill.
(a) what is the speed of the ball when it is halfway down the hill?
(b) at the halfway point (height h/2), the hill becomes smooth, so there is no longer any friction between the hill and the sphere. what is the speed of the ball at the bottom of the hill?

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.
