A famous golfer strikes a golf ball on the ground, giving it an initial velocity v = v0xi + v0yj. Assume the ball moves without air resistance and its motion is described using a Cartesian coordinate system with its origin located at the ball's initial position. show answer No Attempt 25% Part (a) Determine the vertical component of the initial velocity, v0y, assuming the ball reaches a maximum height of 28 during the drive. Give your result in m/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.
