A ball is thrown horizontally from the top of a 50.5-m building and lands 104.8 m from the base of the building. Ignore air resistance. (Assume the ball is thrown in the x direction and upward to be in the y direction.)a. What must have been the initial horizontal component of the velocity? b. What is the vertical component of the velocity just before the ball hits the ground? c. What is the velocity (including both the horizontal and vertical components) of the ball just before it hits the ground?

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.
