Q. A 5.0 multiplied by 102-newton girl takes 10. seconds to run up two flights of stairs to a landing, a total of 5.0 meters vertically above her starting point. What power does the girl develop during her run?

Q. A large uniform "butcher block" rests on two supports and has a weight hanging from its end. The block has a mass of 100 kg and a length of 2 meters. If L = 1.27 meters and the hanging weight is 153 newtons?

what is the force on the right support?

what is the minimum value for the hanging weight to the nearest tenth of a kilogram if L = 1.7 meters and the configuration is to remain stable"
