5.A coin is placed 0.100 m from the center of a vinyl record. a. If the coefficient of friction between the record and coin is 0.124, what is the maximum
speed that the coin can have before it slides off of the record?
Given:
R =
U =
g = 9.8 m/s^2

Unknown:

V=?

Equation:

V^2 = u r g

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.
