A 4.29 kg ball is dropped from the roof of a building 151.1 m high. While the ball is falling to Earth, a horizontal wind exerts a constant force of 14.0 N on the ball. How long does it take to hit the ground? The acceleration of gravity is 9.81 m/s2 .
Answer in units of s.

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.
