The mass center G of the 1305-kg rear-engine car is located as shown in the figure. Determine the normal force under each tire when the car is in equilibrium. State any assumptions. -1264 mm-863 mm Answers: Normal force under each of the front tires: N₁= N Normal force under each of the rear tires: N₁ = N i i

A rope is hanging off the edge of a building that is 10 meters tall. The rope extends the entire side of the building and just touches the ground. If the rope has a mass of 2 kg total, and the acceleration due to gravity is m 9.8 s2 what amount of work is done winching in all the rope to the top of the building? (Just
