Cole and blayne were attempting to push hailey on a wheeled chair with enough force so hailey would run into mr young. they figured out they needed a 50 n force to run the chair into mr young. cole and blayne were both applying force toward mr young. cole was applying force a 20 n force to the left, and blayne was applying (with all of his strength) a force of 15 n to the left. what was the net force if we ignore friction?

The magnitude of the amount of energy released by burning a fuel source, measured in energy per unit mass, is called its fuel value. note that the fuel value is the negative of the isobaric specific heat of combustion for the fuel. if all the energy obtained from burning 1.23 pounds of butane with a fuel value of 10.85 kcal/g is used to heat 128.0 kg of water at an initial temperature of 18.3 °c, what is the final temperature? note that 1 lb = 453.6 g.
