8. A product was determined to have a critical acceleration of 50 g. You are to design a cushion to protect the product from as many as four drops from 18 inches. Using the cushion curves in the appendix, determine the most cost-efficient foam cushioning solution using (list a single thickness and static load)?

QUESTION 9 Water comes down the spillway of a dam from an initial vertical height of h=144 m. What is the highest possible speed of the water at the end of the spillway? Assume g = 9.81 m/s² h

E15. Water emerges from a faucet at a speed of 1.5 m/s. After falling a short distance, its speed increases to 3 m/s as a result of the gravitational acceleration. By what number now would you multiply the original cross-sectional area of the stream to find the area at the lower position?hoto

As a hiker in Glacier National Park, you are looking for a way to keep the bears from getting at your supply of food. You find a campground that is near an outcropping of ice from one of the glaciers. Part of the ice outcropping forms a slope of angle ? up to a vertical cliff. You decide that this is an ideal place to hang your food supply, as the cliff is too tall for a bear to reach it. You put all of your food into a burlap sack, tie an unstretchable rope to the sack, and tie another bag full of rocks to the other end of the rope to act as an anchor. The mass of rocks that you put into the anchor bag is equal to the mass of food in the other bag. What will be the acceleration ? of the food bag when you let go of the anchor bag? Assume that the weight of the rope is negligible, and that the ice can be considered frictionless. Express the resulting acceleration ? of the food bag in terms of ? and ?, the acceleration due to gravity. Let the positive direction for this bag be downwards.
