Two pieces of clay are moving directly toward each other. when they collide, they stick together and move as one piece. one piece having mass 300 g is moving to the right at a speed of 1 m/s. the other piece has mass 600 g and is moving to the left at a speed of 0.75 m/s. a) use momentum conservation to determine the velocity of the combined clay piece after they collide. (note: you can treat this as a one-dimensional problem, but since you're computing velocity not speed, you need to include an appropriate sign. assume the positive axis points to the right; therefore use a positive sign to indicate motion to the right, and a negative sign to indicate motion to the left.) -0.167 m/sb) what fraction of the total initial kinetic energy is lost during the collision? in other words what is (kei−kef)/ kei?

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.
