PLEASE ANSWER THESE 2 FOR PHYSICS ASAP A racecar driver drives on a straight track (with friction). He pushes on the brake and the car slows down. What is happening to the kinetic energy of the car as he applies the brake.
The kinetic energy disappears

The kinetic energy is converted into chemical potential energy

The kinetic energy is converted into thermal energy

The kinetic energy stays constant

A cart is moving on a track and slows down because of friction. Select all of the following statements that explain why the cart slows down. [You can select more than one answer]
kinetic energy from the cart is converted to thermal energy in the cart

chemical potential energy in the cart is converted to kinetic energy in the track

kinetic energy from the cart is converted to thermal energy in the track

kinetic energy from the cart is converted to chemical potential energy in the cart

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.
