Can u answer all of the question a) b) c) d and e plz 8. Before the invention of the electric refrigerator in 1913, people kepttheir food cool with blocks of ice in the home. a) Calculate the workneeded to lift a 446-N block of ice a vertical distance of 2-m. b) What PEdoes the block have? c) When the same block of ice is raised the samevertical distance by pushing it up a 5 m ramp, only 178.4 N of force isrequired. Calculate the work done to push the block up the 5m ramp. d)What PE does it have? e) Draw a sketch of the ramp and determine theMechanical Advantage of the ramp.

work done = Fx potential energy = - work done by conservative force

Consider the following scenario. A car for which friction is not negligible accelerates from rest down a hill, running out of gasoline after a short distance. The driver lets the car coast farther down the hill, then up and over a small crest. He then coasts down that hill into a gas station, where he brakes to a stop and fills the tank with gasoline. Identify the forms of energy the car has, and how they are changed and transferred in this series of events. (See Figure 7.34.) Figure 7.34 A car experiencing non-negligible friction coasts down a hill, over a small crest then dill again, and comes to a stop at a gas station.
In Chapter 7, the work-kinetic energy theorem, W = K, was introduced. This equation states that work done on a system appears as a change in kinetic energy. It is a special-case equation, valid if there are no changes in any other type of energy such as potential or internal. Give two or three examples in which work is done on a system but the change in energy of the system is not a change in kinetic energy.
