The Hopping Hamster roller coaster starts with a velocity of 5m/s at point A.  The roller coaster, with the passengers, has a mass of 2000kg. Use the diagram below to answer the following questions. Enter the numbers and units into the box. Supposing there is no friction, what is the speed of the roller coaster at point B in m/s? m/s Supposing 25kJ of thermal energy is released between points A and B, what now is the speed of the roller coaster at point B in m/s? m/s

You want to make a life size mobile of famous cartoon characters to greet people outside of a museum.  You have a Mickey Mouse that has a mass of 10lbs, an Olive Oyl that is 8lbs, a Charlie Brown that is 12 lbs, and a Velma Dinkley that is 11 lbs.  You have a 30ft rod whose center of mass is at the center of the rod.  If Mickey Mouse is placed at the 10ft mark and Olive Oyl at the 18ft mark and Charlie Brown at the 8ft mark, where should you place Velma Dinkley to balance this hilarious mobile?   At which mark, in feet, should we place Velma Dinkley?  Enter only the number into the box.
